Array Status:_________________________Warning
Firmware Revision:_______________38370HP20P1007041848
Product Revision:_____________________HP20
Last Event Log Entry for Page 1:______124018

Stephen,

You have scsi errors on your disks.
Are all the leds on the VA7400 are ok.

It seems that you have serious problems.
Is the VA covered by an HP support contract?

[stephen peng]

Luk,
thank you for your reply.
all the leds of the array are ok, maybe the failed disk led to that problem i though, and io requests on the filesystem which created on the disk group where the failed disk belong to were just serious, and the io average wait number are high.
unfortunately, the array is not covered by HP contract.
