HP StorageWorks 9100 Extreme Data Storage System administration guide V1.0.2 (AN540-96018, February 2010)

HP ExDS9100c enclosure front panel fault ID LED is amber
If the HP ExDS9100c enclosure fault ID LED is amber, check to see if the power supplies and controllers
are amber. If they are not, wait until a suitable time and power cycle the storage block. In the meantime,
the enclosure fault LED can be ignored. If the power supplies and controllers are amber, see the HP
StorageWorks 9100c Extreme Data Storage System user guide for troubleshooting steps.
Path from server to all arrays is “none”
NOTE:
This section does not apply to HP ExDS9100 Storage System V1.0.2v2.
Sometimes a server is not able to access any storage block. You may notice this because the following
symptoms are present:
• Paths from the server to all controllers have a status of none (as shown by the exdsmgr show
array <number> command).
• No LUN has the server in it in the visible to field (as shown by the exdsmgr show lun
command).
• The server cannot join the Matrix.
The symptoms in this situation indicate that the P700m SAS HBA has failed. However, before concluding
that the P700m has failed, perform the following procedure, checking the status after each stage.
IMPORTANT:
HP recommends that you perform this procedure during a scheduled maintenance window; otherwise,
ongoing I/O operations on other server blades could be affected.
1. Reboot the affected server blade.
2. Log in to the Onboard Administrator and run the show bay info all command. Compare
entries for the affected blade and working blades.
3. If the entries look different, reboot each Onboard Administrator, one at a time.
4. re-seat or replace the P700m in the affected server blade.
Please refer to section Apparent failure of P700m for additional information.
Spare disk drive not illuminated green when in use
Spare disk drives might not always be illuminated green, even when they are in use.
IMPORTANT:
Do not remove a disk drive unless the fault/UID LED is amber.
