This software supports ETERNUS SN200 series Fibre Channel switch, Brocade Fibre Channel switch, Fibre Channel switch with ETERNUS GR740D installed, and PRIMERGY BX600 Fibre Channel switch blade.
The settings that must be directly defined on the device side before this software manages these Fibre Channel switches are explained below. For details, refer to the manual supplied with the respective device.
Define the IP address, subnet mask, and gateway address for a LAN. If the Fibre Channel switch is equipped with an operation panel, these settings can be defined from the operation panel. If the Fibre Channel switch is equipped with a serial port, define them by issuing the ipAddrSet command via the serial port.
For Fibre Channel switch control, this software is used to log in using telnet to the device. Control requires a user name and password of the administrator security level. The factory default settings of user name and password are "admin" and "password", respectively.
If the password has been changed on the device side, this software recognizes the change and displays the device icon as a warning when [Refresh] is selected. Also, the monitoring status of the device becomes "invalid Password".
In order for the setting to match the changed device setting, select the device icon in the domain view of the physical resource view, and select [Device] - [Change account for device management] from the main menu.
For some types of devices, the change of the password on the device side cannot be recognized automatically, and the status does not become "invalid Password". Click [Device] - [Change account for device management] in the main menu for these devices as well.
When connected to a cascade, some types of devices cannot automatically recognize the changed password; therefore the status doesn't become "invalid Password". In this case, delete the device and register it again. Refer to "5.2 Registering device" for details on deleting and registering devices.
A domain name is a unique name defined for a Fibre Channel switch in a SAN. Such names are necessary for a cascade connection of multiple Fibre Channel switches. Since domain names are automatically defined by firmware built into the individual Fibre Channel switches, the name need not be considered during definition and management of access paths using this software.
However, the domain names are important elements in manual port zoning. In such cases, make sure that no identical value is set for any two Fibre Channel switches in the cascade connection. If a Fibre Channel switch is equipped with an operation panel, a domain name can be set from the operation panel. If a Fibre Channel switch is equipped with a serial port or if network settings are defined for the Fibre Channel switch, log in to the switch, and set a domain name by executing the configure command.
Register a switch name for Fibre Channel switch control. This software uses this switch name as SysName. SysName should be a name that is not identical to any other name registered with this software. If the Fibre Channel switch is equipped with an operation panel, a switch name can be set from the operation panel. If the Fibre Channel switch is equipped with a serial port or if the network settings are defined for the Fibre Channel switch, log in to the switch, and set a switch name by executing the switchName command.
Zoning is recommended. Zoning is not required for the GR740D built-in Fibre Channel switch.
No zoning is set for Fibre Channel switches by factory default. When such Fibre Channel switches are connected to server nodes or storage devices, they are placed in a state where their security levels are undefined (which makes all of the Fibre Channel switches accessible from every server node). To prevent inadvertent access from destroying data on the storage side, do not make an attempt from the server node to make write access to a storage device by using the format or other command, until an access path is defined by this software.
If suppression of write access attempts is not guaranteed, thereby allowing data to be written inadvertently to the storage device, stop all access paths of the Fibre Channel switches by creating a temporary zone using telnet as shown below. After defining this setting, connect the server node and storage device to the Fibre Channel switch, and set up an access path using this software. When setting up a cascade connection between the Fibre Channel switch and another Fibre Channel switch for which zoning is already set, you need not define this setting because zoning information is copied. The setting is also not necessary if the Fibre Channel switch is to operate without the zoning setting.
zoneCreate"SNM_0001","00:0B:00:00:0E:00:00:00;00:0C:00:00:0E:00:00:00" cfgCreate"SNM_BCSI","SNM_0001" cfgEnable"SNM_BCSI" cfgSave
If the Fibre Channel switches are to be cascaded for operation, cascade the switches before executing the above command. Execute this command on a Fibre Channel switch where the latest firmware has been installed.
Create a temporary zone when using the host affinity and zoning operation command (storageadm zone). For details, refer to "12.1.1.5 Host affinity and zoning operation command (storageadm zone)".
If this zone has been created, all accesses will be blocked. For this reason, do not implement this measure while the target Fibre Channel switch environment is operating. Implement this measure either immediately after the Fibre Channel switch environment has been installed and before operations have started (or while operations are paused).
This software communicates with the Fibre Channel switch by using "public" or "private" for the SNMP Community name. To change the SNMP Community name, change the settings on the device side, and adjust the settings of this software accordingly. For information about changing the Community name, refer to "SNMP_COMMUNITY_NAME_FOR_IP" in the "C.2 sanma.conf Parameter".
For the SNMP-MIB setting of the Fibre Channel Switch (except for the ETERNUS SN200 model 250M and Brocade AP7420), set the following by specifying the telnet command snmpMibCapSet. Specify "yes" for the "FA-MIB" and "SW-TRAP" items. Leave the other items unspecified. Simply press ENTER for these unspecified items.
sn200:admin> snmpMibCapSet The SNMP Mib/Trap Capability has been set to support FE-MIB SW-MIB SW-TRAP FA-TRAP FA-MIB (yes, y, no, n): [no] yes SW-TRAP (yes, y, no, n): [yes] yes FA-TRAP (yes, y, no, n): [yes] SW-EXTTRAP (yes, y, no, n): [no] Committing configuration... done. sn200:admin>
The output of the above command may depend on the firmware version of the Fibre Channel switch. Change the settings of only the "FA-MIB" and the "SW-TRAP" items.
If "FA-MIB" is not "yes", physical connection information, port zoning information, and port speed (transfer rate) information on each port of the Fibre Channel switch is erroneously recognized. Additionally, the fault monitoring function does not run if "SW-TRAP" is not "yes".
This software uses the one-to-one WWPN zoning of the Fibre Channel switch as the basis for setting up and removing access paths (logical paths). However, it also supports other types of zoning settings at their respective levels. The functions that it supports for the different types of zoning are as follows:
This is a state that has no zoning setting. In this state, the Fibre Channel switch permits access between all ports. It is the factory default setting. However, if a Fibre Channel switch is connected in cascade to another Fibre Channel switch with a zoning setting, the zoning setting information is copied when cascade connection communication is established.
This software can perform management normally for the Fibre Channel switches without a zoning setting. Also, when registering a Fibre Channel switch with this software, you can specify whether to set zoning in response to a subsequent software attempt to set up an access path.
With no zoning setting, the Fibre Channel switch operates with security management delegated to the binding and affinity capabilities of server nodes and storage devices.
The WWPN zoning setting is a method by which zoning is defined based on the WWPN of a Fibre Channel port. A WWPN value that is unique throughout the world is defined for each port. As a result, no wrong access path is created even if the port connection place of the Fibre Channel switch is changed.
All access path control functions of this software are effective for access paths defined in the one-to-one WWPN zoning setting. For other defined access paths, this software can read access and display path information, but it cannot delete the access paths. To delete an access path, use the zoning information in the Fibre Channel switch properties, or Fibre Channel switch Management Software, or the telnet capability of the Fibre Channel switch.
The port zoning setting is a method by which zoning is defined based on the specification of the port connection place of the Fibre Channel switch. A new port zoning setting must be defined if the port connection place of the Fibre Channel switch is changed.
As for the access path control functions, this software can read information about access paths for which port zoning is set, display the paths, and manage their status, but it cannot delete the access paths. To delete an access path, use the zoning information in the Fibre Channel switch properties, Fibre Channel switch Management Software, or the telnet capability of the Fibre Channel switch.
The WWNN zoning setting is a method by which zoning is defined based on the WWNN of a Fibre Channel port. Though a WWNN can be shared by several Fibre Channel ports, its definition differs from company to company.
As for the access path control functions, this software cannot display or delete access paths for which WWNN zoning is set. However, it can perform fault management of the Fibre Channel switch.
Different types of zoning settings can be defined for the Fibre Channel switch. To allow this software to provide complete zoning security, however, changing the existing zoning setting to the one-to-one WWPN zoning setting is recommended.
The zoning setting can be defined in the Zone Administration window of WEBTOOLS of the Fibre Channel switch. Note that settings in WEBTOOLS are dependent on the device and firmware.
For example, in the WEBTOOLS window of SN200M40 (v2.4) shown below, WWPNs are the values indicated by blue round disks on the Member Selection List and WWNNs are the values displayed next to the folder icons above the blue round disks.
Check whether the SNMP Community settings on the device side agree with the settings of this software. For details, see "SNMP community setting".
For devices that do not support [Detect device in subnet] as described in "1.3.7 Support levels", use [Detect by IP address] with the IP address specified.
Check whether the Ethernet port communication speed has been set correctly.
When the SNMP connection authorization list is set up, make sure to include authorization for access from the manager.
Check whether all the Fibre Channel switches connected in cascade are registered in this software. Register all the Fibre Channel switches that have not been registered.
If the network communication with the device is disabled, the physical connection line cannot be displayed. Make sure that the device is powered on and there is no problem with the LAN connection. Furthermore, check whether the SNMP Community settings on the device side agree with the settings of this software. For details, see "SNMP community setting".
If the network communication is disabled because of device replacement or maintenance, the physical connection line is not displayed.
Check whether a hardware error (FC port, FAN, power supply, temperature, etc.) has occurred.
Check whether a monitoring status in device properties is "invalid Password". If so, the password on the device side has been changed. Refer to "User name and password for Fibre Channel switch control" and change the registration information of this software.
When the device is powered on or rebooted, initialization is performed in the device. While the initialization is being performed, if [Refresh] is executed, a warning message for the device may appear. If no error occurs on the device, execute [Refresh] again after the initialization of the device. The display then becomes normal (in green).
There is no zoning setting for configuring the access path.
If a monitoring status in device properties is "invalid Password," see "A warning for a device is displayed (in yellow).".
See "SNMP community setting".
If a device network is not accessible, the device icon will disappear from the domain view. Refer to "The physical connection line of the FC cable is not displayed." for details. In this case, the device may be displayed on SAN view.
Check whether there are zoning settings in the Fibre Channel switch that is connected to PG-FCD101 or PG-FCD102. If there are no zoning settings, refer to "Zoning setting" and then create a temporary zoning.
Note
The ETERNUS SN200 series, Brocade Fibre Channel switch can define six monitoring device addresses (SNMP Trap transmission places) per device and a different SNMP Community name for each of these addresses. This software uses "public" for the entry that is set for the SNMP Community name. If this entry is already used, this software overwrites it. If the SNMP Community name on the device side has been changed from "public" and the settings of this software have been changed accordingly, the entry with the changed SNMP Community name is used.
The ETERNUS SN200 series, Brocade Fibre Channel switch features the QuickLoop function that accomplishes FC-AL hub emulation. However, this software does not support Fibre Channel switches for which this function is enabled.
This software can control access paths to the GR740D (including the Fibre Channel switch). Note that the Fibre Channel switch of the GR740D cannot be connected in cascade to another Fibre Channel switch.
This software communicates with the Fibre Channel switch using SNMP and telnet.
It is recommended of Fibre Channel switch redundancy (cascading).
At present, the Fibre Channel switch zoning information cannot be restored from the database of this software. Therefore, multiple Fibre Channel switches must be connected in cascade to prevent the zoning information stored on the Fibre Channel switches from being erased. The zoning information is stored separately on each of the Fibre Channel switches connected in cascade. Even if one of the Fibre Channel switches fails, the zoning information is stored by the other switches.
The Fibre Channel switch zoning information is changed using the access path setting. When cascade connection is not used, be sure to save the device configuration information (configUpload file) after making changes in the settings. For details on storing configuration information, refer to the manuals that come with the device.
However, cascade connections should not be implemented between two or more ETERNUS VS900 model 300.
To manage Fibre Channel switches with this software, all the Fibre Channel switches that are connected in cascade must be registered with this software. If any Fibre Channel switch is connected in cascade but not registered with this software, the SAN environment cannot be correctly managed.
Use the manual embedding function to register the ETERNUS SN200 model 250M and Brocade AP7420 Fibre Channel Switches as Fibre Channel Hub devices. This registration makes SNMP Trap fault monitoring available to the Fibre Channel Switches.
In consideration of incompatibility of Fibre Channel switch firmware, this software checks the firmware version number.
If this software detects firmware that it does not support, all functions including the configuration management is restricted.
The following message is output to the event log. (XXXXXX is the version number of the detected firmware.)
"Unsupported Firmware Version XXXXXX"
Contact your Fujitsu CE or SE because patches need to be applied to this software.
The FC routing function is not supported.
If a cascade is connected using the FC routing function, the cascade connection line is not displayed in the client window.
For this reason, an error is displayed (in Red) for the access path that goes through the cascade connection line, and a warning is displayed (in Yellow) for the server node that is used to configure the access path.
For GbE ports that are used in the FCIP tunneling function, 8 virtual ports per single GbE port are displayed in the client window.
A warning is displayed (in Yellow) in the client window for the FC ports for which the FCIP tunneling function is disabled. Monitor the occurrence of errors using SNMP Trap.
This software does not support the Administrative Domain (Admin Domain).
