This software can delete access paths set by it and access paths for which one-to-one WWPN zoning is set for Fibre Channel switches. It can delete access paths only in the Fibre Channel switch environment.
Such an access path can be deleted even if the access path state is Config miss Match. Select and delete the access path whose state is Config miss Match in the window.
Delete an access path for which one-to-one WWPN zoning is set for a Fibre Channel switch between server nodes (HBAs) or between storages (CAs) according to the zoning information in Fibre Channel switch properties.
The access path cannot be deleted to change the zone status of the switch to non-zoning (No Security). All the zoning settings of the switch are deleted when a user request to delete an access path is processed, this software creates a dummy zone. Although the loss of zone security as a result of deleting zoning can lead to inadvertent accessing of disk areas during operation, the dummy zone created prevents data destruction.
When changing the zone status of the switch to non-zoning (No Security), manually change the zone status of the switch to No Security. Note that this dummy zone will not be deleted even if access path addition processing is executed.
Notes
Only an administration account, whose authority level is "privileged administrator", can delete access paths.
You cannot delete access paths defined during setup other than for setting one-to-one WWPN zoning such as port zoning, WWNN zoning, or multi-port WWPN zoning in a Fibre Channel switch. (Only the one-to-one WWPN zoning setting is valid in this software.) In such cases, delete a zone from the zone information of Fibre Channel switch properties, or log in directly to the Fibre Channel, and change the setup.
Select [View] - [Refresh] from the menu or press [F5] key, and verify that all Fibre Channel switches cascaded to the Fibre Channel switch associated with the access path setting can be correctly recognized in the current status. Once an access path is changed because a Fibre Channel switch is temporarily disconnected from the cascade connection, the old cascade connection cannot easily be recovered. (In this event, execute the cfgClear command to delete zoning information for the Fibre Channel temporarily disconnected from the cascade connection. This enables cascade reconnection.)
When deleting an access path that is configured in the FC routing functionality LSAN zone in this software, manually delete the LSAN zone in the device in advance.
Server node setting
If Fujitsu multipath disk control mechanism or msdsm on the Windows server node, be sure to shut down the server node before deleting an access path. If an access path is deleted while the server node is in operation, a very long time is required to shut down the server node later because of the operation of Windows path detection logic.
To delete the access path of Fujitsu multipath disk control mechanism or msdsm on the same server node as the admin server from this software, shut down the admin server, disconnect the FC cable from the access path to be deleted, restart the admin server, and delete the access path.
For Unix, execute umount for the access path to be deleted.
Physical removal
When ETERNUS Multipath Driver 2.0.1 or higher is used and the access path to be deleted is physically connected to a Fibre Channel switch for which no zone is set, physically remove the access path in advance such as by disconnecting the cable for which access path deletion is to be executed.
Delete a set access path. You can also delete the access path whose state is [Config miss Match] (incorrectly set access path).
[Solaris OS (GR Multipath Driver, MPLB, MPHD environment)] Release the multipath setting.
Refer to the relevant driver's manual for information on the command and command parameters.
If GR Multipath Driver or MPLB 2.2 and higher, execute the following command:
# mplbconfig (arguments are required, -d option)
If MPLB 2.1 and former or MPHD, execute the following command:
# iompadm (arguments are required , destroy option)
MPLB2.1 or earlier and MPHD do not support the commands that add and remove paths. Delete the multipath instance by using the above command (iompadm destroy).
[Solaris OS (GR Multipath Driver, MPLB, MPHD, HDDV environment)] Release HDDV.
When the hot system expansion function of server node is disabled, execute the following commands:
# hddvadm -i
hddv.conf is moved to sd.conf, and the mphd.conf/mplb.conf file is saved.
[Windows] If Fujitsu multipath disk control mechanism or msdsm is set, shut down the Windows server node. If the Windows server node is active in this environment, this software suppresses access path deletion.
In this software, click the target access path, and select [Operation] - [Access Path] - [Delete] from the menu. Alternatively, click the target access path to select it, right-click it, and then, select [Access Path] - [Delete] from the pop-up menu.
Select the displayed access path to be deleted. Then, click the <OK> button to confirm deletion and delete it. (When an access path used for Windows 2000 or Windows 2003 is deleted, a warning message appears as many times as the number of LUNs set for the access path.)
[Solaris OS (Agent available)] After the access path has been deleted, its state may remain Config miss Match (yellow) until the server node is restarted. (If WWPN binding is set on the server node)
[ETERNUS Multipath Driver 2.0.1 or higher] Execute the grmpdautoconf command to implement path removal.
(For details of the command specifications, see the ETERNUS Multipath Driver User's Guide.)
# /usr/sbin/grmpdautoconf -d
Note
If the HBA is the PW008FC2A, PW008FC2-G, PW008FC3, GP7B8FC1A, GP7B8FC1-G, GP7B8FC1, SE0X7F11F, SE0X7F12F, the port property described in /kernel/drv/fjpfca.conf may be deleted by executing the grmpdautoconf command. After executing the grmpdautoconf command, reset the property as needed. For details on the setting contents, see "4.1.1 Solaris OS server node (host)".
[GR720, GR730 (version V11L21 or earlier), GR740, GR820, GR840 (version V03L52P1939 or earlier)] Restart the GR device. The device must be restarted to reflect the GR settings defined from this software. However, unspecified versions and some of the GR740, GR820, GR840 P19 versions (for these versions, contact Fujitsu) need not be restarted because the GR side supports the hot system configuration setting reflection function.
[Solaris OS] Follow the procedure below so that the server node recognizes the storage unit.
In the hot system expansion (hddvadm -M) environment of ETERNUS Multipath Driver 2.0.1 or higher, GR multipath driver, MPLB, MPHD, or HDDV, execute the command shown below. After path removal, the server must be restarted to enable the Fibre Channel card definition of the server node.
# /usr/sbin/shutdown -y -i6 -g0 (restarts the server) # disks -C (execute with Solaris 7 OS or higher)
In an environment using the GR multipath driver, MPLB2.2 or later, MPHD, and HDDV with non-hot system expansion or normal specified (hddvadm -m), execute the following operations:
If the deleted target ID is not used in the sd.conf file, edit sd.conf to delete the target ID. (Do not delete it if it is used by another device.)
#touch /reconfigure
# /usr/sbin/shutdown -y -i5 -g0
Start it in single user mode.
# hddvadm -m (The required part of sd.conf is moved to hddv.conf, and the saved mphd.conf/mplb.conf file is restored.)
#touch /reconfigure
#/usr/sbin/shutdown -y -i6 -g0 (Instances for each driver (mplb/mphd/hddv) are configured when the definition file is restored.)
# disks -C (execute with Solaris 7 OS or higher)
In an environment using MPLB2.1 or earlier
If the deleted target ID is not used in the sd.conf file, edit sd.conf to delete the target ID. (Do not delete it if it is used by another device.)
#touch /reconfigure
# /usr/sbin/shutdown -y -i5 -g0
Start it in single user mode.
# hddvadm -m (The required part of sd.conf is moved to hddv.conf, and the saved mphd.conf/mplb.conf file is restored.)
#touch /reconfigure
# /usr/sbin/shutdown -y -i6 -g0
# disks -C (execute with Solaris 7 OS or higher)
Reconfigure the multipath by using the new #iompadm command.
In an environment where neither the hard disk driver (HDDV) nor multipath control (GR multipath driver, MPHD MPLB) is used
#touch /reconfigure
# /usr/sbin/shutdown -y -i6 -g0
# disks -C (execute with Solaris 7 OS or higher)
Check the access path from this software.
[Windows] Restart the device.
[Linux] Restart the device.
[HP-UX] Restart the device.
[Other server nodes] Perform operations for device deletion recognition.
When the operating system is VMware Infrastructure 3 Version 3.5 (or later) or VMware ESXi 3.5 (or later), reboot the VM host or execute "Rescan" for the HBA that the access path has been set by using VMware Infrastructure Client. For the using method of VMware Infrastructure Client, refer to "Access path management" of "Configuration management" in "4.1.7.2 VMware Infrastructure 3 Version 3.5 (or later) or VMware ESXi 3.5 (or later)".
Storage affinity (WWPN binding) is deleted but LUN settings of the related /kernel/drv/sd.conf file are not deleted in consideration of security. If a definition must be deleted, edit the /kernel/drv/sd.conf file directly on the server node side.
