HP AutoRAID hanging with 1 lost disk
I have an HP 9000 - HP-UX 11. With HP AutoRAID array:
11x9GB drives
Logical capacity 70725MB
Unallocated 0MB
Active spare 8638MB
Data redundancy 16107MB
Total 95515MB
Active spare enabled
Auto-Rebuild enabled
Rebuild Priority high
We lost a disk on the system, and for a while I/O continued with messages in the hparrary logs:
Controller error record for Subsystem 0000001371ED at Sat Jun 5 02:14:04 2004
Controller timestamp = 2808172
Event code = 166
Event code description = Internal SCSI Event
Event count = 1
Component ID = 7
FRU ID = 9
FRU description = Disk in slot B5
Controller error record for Subsystem 0000001371ED at Sat Jun 5 02:14:04 2004
Controller timestamp = 2808172
Event code = 98
Event code description = Read Recovered With RAID 5 Redundancy
Event count = 1
Component ID = 7
FRU ID = 129
FRU description = Reporting Controller
...etc
Then all filesystems associated with the array became unavailable. Applications using the filesystems started to hang. No more messages in the hparray logs.
This state continued for several hours until hardware vendor could arrive and replace the disk. I/O was available shortly after. The auto rebuild completed later OK.
I dont understand why with an active spare and RAID 5 redundancy, the luns were totally unavailable with only 1 lost disk.
Am I missing something here?
Thanks
Aaron

Re: HP AutoRAID hanging with 1 lost disk
I am not familiar with this type of array, but a defective disk drive can block an entire SCSI bus.

Re: HP AutoRAID hanging with 1 lost disk
Dont suppose you know if this behaviour (hanging SCSI bus due to failed array disk) is documented anywhere?

Re: HP AutoRAID hanging with 1 lost disk
So I guess the bad disk hang the internal SCSI bus of the AUTORAID. I have also seen Jamaica disk (JBOD) failure which hang the entire FWD SCSI bus as well.
