SMH Disks show degraded

[Andrew medhurst1]

guys i have an issue with SMH( why did HP change it from sam ?????? AAAAARGH)
it shows the two hardware raid luns as degraded but all my checks show as fine with no problems.
can someone tell me what the hell this stupid web interface thinks it is checking to say that the disks are degraded.
when i go in under the tools section ( i.e. bits of sam) it tells me the disks are ok but on home screen they still say degraded, any ideas gratefully recieved.
regards

hi,

the question is :

do you have a HW raid or LVM mirror on the disks.

if its a HW raid you have for example 4 physical disk but the system see only 2 disks.

if you have a LVM mirroring, with 4 physical disk you will see 4 disk. So if this is you case run

grep EMS /var/adm/syslog/syslog.log

ioscan -fn | grep NO_HW.

thanks for the reply, but as i stated there are 2 hardware raided luns, each with 2 disks, but from OS point of view it only sees the lun presented.
i have run multiple checks and can find no error.
the issue will be monitoring by operations.
can any one tell me what it is checking to think they are degraded.

hi,

ok the HW raid presnet the bundle of disk ajs a 2 logial disk, so the HP-UX don;t care about the HW layout, but SMH check all units on the HW layout.

Hi Andrew,

Please check if you have recived any events in /var/opt/resmon/log/event.log

or in SMH Tools>Event viewer>

if you have any critical events, then you will see the status of the disks as degraded.

Thanks
