If a fault occurs on a device, an error description of the fault is output to the event log in Web Console, the device status is also changed to [Error] or [Warning] if the support level of the device is A or B. The criteria of [Error] and [Warning] depends on the device definition. If this product can identify an access path affected by the fault, the access path status is changed to [Error].
For a device whose support level is I, an error description of a fault on the device is not output to the event log. The color of the device status also remains unchanged.
On Web Console, check for faults in the order shown below and take corrective actions as required.
For middleware errors not including server node HBA and multipath faults, only events are reported. To troubleshoot middleware errors, refer to the appropriate middleware manuals.

Moreover, the replacement of failed components, contact a Fujitsu customer engineer as required.
If Manually Embedded Disk Storage System Is in [Unknown] State
For NetApp FAS Series and FAS Series (with clustered Data ONTAP)
Review network environments and SNMP settings.
If the above action does not solve the fault, check the operation mode of the target device registered on the ETERNUS SF system. If the operation mode is wrong, delete the target device from the ETERNUS SF system once, and re-register it in a proper operation mode. To check operation mode, refer to "Display Storage Device" in the Web Console Guide. For operation mode to be registered on the ETERNUS SF system, refer to "5.2.7 Registering Manually Embedded Device".
Devices other than those above
Review network environments and SNMP settings.
If Manually Embedded Tape Library Is in [Error] or [Warning] State
On the global navigation tab, click Storage.
On the Storage pane, click Tape Library(Manual).
On the Main pane in the manually embedded tape library overview screen, click the target name.
On the Main pane in the manually embedded tape library details screen, click the target name.
The Maintenance screen for the tape library is started. Find the failed component in the tape library.
For replacement of failed components, contact a Fujitsu customer engineer.
When replacing adapters (CA), refer to "If the adapter (CA) of manually embedded disk storage system and manually embedded tape library is replaced" in "10.3.3 Replacing Faulty Components of Manually Embedded Device". Moreover, the replacement of failed components, contact a Fujitsu customer engineer.
If Fibre Channel Switch Is in [Error] or [Warning] State
On the global navigation tab, click Network.
On the Main pane in the switch overview screen, click the target name.
On the Main pane in the switch details screen, click the target name.
The Maintenance screen for the Fibre Channel switch is started. Find the failed component in the Fibre Channel switch.
For replacement of failed components, contact a Fujitsu customer engineer.
If any port is in Error state due to SFP failure, the status of the affected access path is displayed as [Error].
If an access path is defined in the access path settings of this product, the zoning setting of the Fibre Channel switch is defined as WWPN zoning. Therefore, if a Fibre Channel switch port fails, the Fibre Channel cable connected to it can be reconnected to another Fibre Channel switch port, and operation can be restarted.
Also, refer to the following sections as required.
Fibre Channel Switch in Use | Reference Section |
|---|---|
Brocade Fibre Channel switch | "Warning for device is displayed" in "B.4.2.1 Brocade Fibre Channel Switch" |
VDX series |
If Server Node Is in [Error] or [Warning] State
On the global navigation tab, click Server.
On the Server pane, click Access Path.
Check the physical pathway of the access path with an [Error] state.
If no Error state device is on the route, check if a Fibre Channel cable along the route is disconnected. If you cannot identify the cause, contact a Fujitsu customer engineer.
On the server node where msdsm (the default Windows multipath driver) is set, the server node enters the [Warning] state even if the single path (an access path that does not have a redundancy configuration) exists. This depends on the msdsm specification. Because the information for the access path that corresponds to the [Error] state disappears from the OS, this product cannot be distinguished from a single path. If access path is configured with the single path, disable msdsm.
Also, refer to "Warning for server node is displayed" in "B.4.1.1 Common to Server Nodes" as required.
If Access Path Is in [Error] State
If an access path of multipath disk control, follow the procedure below:
Obtaining path statuses
Check the current path configuration and status.
I/O stop related to a failed access path
Replacement of failed components (if necessary) or action for the Error
To replace a failed component, contact a Fujitsu customer engineer.
I/O restart of a stopped access path
For an access path not configured using Multipath Disk Control, a job performed with the target used volume is affected. Stop the job and take the appropriate action to resolve the fault. To replace a failed component, contact a Fujitsu customer engineer.
When replacing an HBA, refer to "10.3.1.1 Host Bus Adapter (HBA) Replacement of Server Node".
Point
In the case of an access path configured with multipath disk control, placing the access path offline causes the access path status to be [Error] and may display "Host Agent reports Access Path Status is degraded." as a message of access path failure.
In that case, put the access path back to online, and it returns to its former status.
Actions to Perform after Component Replacement
For devices that do not support automatic updates of the device component status, perform the Reload Conf. operation for the device whose component has been replaced to refresh the current device status.
When the device status is recovered by performing a replacement, the device status returns to and is displayed as the "Normal" state.
For devices that support automatic updates of the device component status, you do not need to perform the Reload Conf. operation. For devices that support automatic updates of the device component status, refer to "2.5 Monitoring Device Component Status".
The status of ETERNUS AX/HX series, ETERNUS AB/HB series, NetApp FAS Series, NetApp FAS Series (with clustered Data ONTAP), NetApp AFF series, and devices registered manually is not automatically recovered. On completion of device recovery, use the following procedure to return the device to the "Normal" state:
On the Action pane for the manually embedded device, click Modify to open the modify screen of the device.
Select "Normal" from the Status list on the modify screen and click Modify.
