[HPADM] [Summary] physical volume powerfailed

In my case ( dev_t=0x1f000000 ) the disk to be replaced is /dev/dsk/c0t0d0.

The explanation you sent is below.

I think I'll be busy this weekend the faulty disk is one of four disks of an
splitted logical volume.

Thanks again
Best regards

The following command will show you the HW path of the disk that is
failing:
# ioscan -f /dev/dsk/c0t0d0

When you see the "dev_t" value, match up the last 6 digits to the hex
numbers in /dev/dsk - in your case, the last 6 digits are 000000, and
that matches the 0x000000 number for /dev/dsk/c0t0d0

Hello there,

Thanks for your suggestions about the powerfailing disk, I'll take the
correcting actions in this order:

- check the scsi cables
- replace the disk
- replace the scsi controller

By the way, given the following message, which disk is supposed to be
replaced ?

May 6 17:20:47 parma2 vmunix: LVM: vg[1]: pvnum=3 (dev_t=0x1f000000) is

I've got the following disks on my system::
