HP StorageWorks XP Remote Web Console Software - Manual (Page 123)

The procedures of resuming the external volume are described as follows.
• Restoring all external LUs in an external array (Check Paths & Restore Vol.)
• Restoring external LUs individually (Check Paths & Restore Vol.)
Restoring all external LUs in an external array (Check Paths & Restore Vol.)
1. In the LU Operation pane, select External Devices in the Device tree. Physically connected external
arrays appear in the Device list.
2. In the Device list, right-click the external array you want to restore the connection to the local
array, and select Check Paths & Restore Vol. The selected external array appears in blue italics
in the LU list and Device list. It also appears in the Preset list.
To check setting details, right-click the setting in the Preset list, and select Detail. To cancel settings,
right-click the setting in the Preset list, and select Delete.
3. Click Apply. A confirmation message appears.
4. Click OK.
The path status in the Path Setting pane changes to Checking. When XP External Storage finishes
checking path status and the external array can be restored, the Status column changes to Normal.
If the external array cannot be restored, the status changes to Blockade.
Restoring external LUs individually (Check Paths & Restore Vol.)
1. In the LU Operation pane, select an external LU group number in the Device tree. Information
about external LUs in the selected external LU group appears in the Device list.
2. In the Device list, right-click the external LU you want to resume the connection to the local array,
and select Check Paths & Restore Vol.
The selected external group number in the Device tree and the selected external LU in the Device
list appear in blue italics. Rows with operations to be performed on appear in the Preset list. To
check setting details, right-click the setting in the Preset list, and select Detail. To cancel settings,
right-click the setting in the Preset list, and select Delete.
3. Click Apply. A confirmation message appears.
4. Click OK.
The path status displayed in the Path Setting pane changes to Checking. When XP External
Storage finishes checking path status and the external LU can be restored, the Status column
changes to Normal. If the external array cannot be restored, the status changes to Blockade.
Restoring external LUs (LDEV Restore)
The external LU's status might be blocked (Blockade) if errors occur during the setting operation or
the volume-formatting process fails. In this case, see
Troubleshooting External Storage XP and restore
the path to the external array according to the troubleshooting procedure. Then execute the Check
Paths & Restore Vol. command to make the external LU in Blockade status usable. If the external LU's
status remains Blockade, even though you restored the path to the external array and executed the
Check Paths & Restore Vol. command, execute the LDEV Restore command to restore the volume.
