Correcting Enclosure IDs
Rescan forces rediscovery of attached disk drives and enclosures. If both Storage
Controllers are online, it also forces re-evaluation of the enclosure IDs of attached
drive enclosures, so that IDs are assigned based on controller A’s enclosure cabling
order. A manual rescan may be needed after system power-up to display enclosures
in the proper order.
A manual rescan is not required to detect when drives are inserted or removed; the
controllers do this automatically. When drives are inserted they are detected after a
short delay, which allows the drives to spin up.
When you perform a manual rescan, it temporarily pauses all I/O processes, then
resumes normal operation. It can take up to two minutes for the enclosure IDs to be
corrected.
To rescan:
1. Verify that both controllers are up.
2. Select Manage > General Config > Enclosure Management > Reorder Enclosure
IDs.
3. In the Reorder Enclosure IDs panel, click Rescan.
Viewing Drive Enclosure Versions
To view the firmware version (revision) and type of expansion modules in each
drive enclosure connected to the system, do either of the following:
● Select Manage > Update Software > Enclosure Firmware > Show Enclosures.
Information is displayed for all drive enclosures connected to the system:
■ Enclosure WWN – The drive enclosure's node World Wide Name.
■ Address – The channel and SCSI ID of the expansion module.
■ Manufacturer – The expansion module manufacturer.
■ Model – The expansion module model number.
■ Revision – The revision code for the firmware currently in the expansion module.
● Select Manage > Update Software > Enclosure Firmware > Show Enclosure Types.
Information is displayed for each type of drive enclosure connected to the system:
■ Vendor/Model – The vendor and model of the expansion module.
■ Firmware Revision – The revision code for the firmware currently in the
expansion module.
