[RAC_1 · Accepted solution]

you have problems with disk-0x1f022000
(c2d2d0) check it.

ll -R /dev/dsk | grep 022000

[Ahmed_58]

Hi RAC,
How did you found the disk id?

Regards,
Ahmed

[Rajeev Shukla]

Yes on of your disk has failed and to identify
ll /dev/dsk/|grep 022000
I can also see some NFS mounts becoming unavailable which could be on the disk in the VG which is no more available.

[Rajeev Shukla]

I dont know about 1f in the 0x1f022000 but from past experience the last 6 digits correspond to the minor number of the disk reported by kernel

[Ahmed_58]

Thanks all for your quick response.

Ahmed
