Hardware problems

Description Details

AX150 and AX150i – If disk module 3 is not a

component of a virtual disk, removing disk module 3

does not cause the storage-system fault light to be

lit. Disk module 3 is one of the minimally specified

set of disk modules for the AX150. Removing it

removes a redundant copy of the FLARE Operating

Environment (OE) software for SP B.

Frequency: Every time disk module 3 is removed if no

virtual disks have a component on disk module 3.

Prevention/resolution: To prevent the issue, do not remove

disk module 3. To resolve the issue, reinsert disk module

AX150 and AX150i – After reboot, although you can

ping one or both SPs, neither SP is accessible for

I/O. The SP boot/fault light on the SP is blinking. This

may also be seen during a reboot due to a software

upgrade of the FLARE OE.

Frequency: Very intermittent

Prevention/resolution: Shut down and restart the storage

system. If this does not work, then see the AX150

hardware troubleshooting trees on the AX150 support

website for the SP boot/ fault light.
