Failing Disk

I am seeing the following errors in the syslog: Can some one please guide me in identifying the failing disk. I guess it is c0t6d0 but when I did the vgdisplay and pvdisplay and ioscan, it seems to be fine.

Re: Failing Disk

Check lvdisplay output and look out that any stale extents are there or not???

Re: Failing Disk

Hi Waqar,

Seems, the lbolt error in your syslog caused due to scsi reset. so, you can use the following commands to check the disk in Question :-

1. Ioscan -fnC disk
2. pvdisplay /dev/dsk/
3. diskinfo /dev/rdsk/
4. dd if=/dev/dsk/ of=/dev/null bs=1024k
5. echo 2400?20X | adb /dev/dsk/

if all the outputs ok, then your disk in good.

Re: Failing Disk

Shalom,

lbolt means one of two things.

* a hot swap disk was replaced and the message will clear next time you boot the system. You might be able to clear it with dmesg -c or dmesg - one of those works on Linux the other on HP-UX and I mix them up.

* A disk is failing. Back up the data if you can and go ahead and replace it now.

Re: Failing Disk

yes, Steven is right.

lbolt tells the failure of the disk. and you can identify that failure with the above said commands.

Re: Failing Disk

hi


the messages tell you dev: 1f006000
#ll /dev/dsk | grep "1f006000"
#ll /dev/rdsk | grep "1f006000"

find out the /dev/dsk/cxtydz

do a pvdisplay -v /dev/dsk/cxtydz

note the VG this belongs to and also note the LVs that this disk caters.

if those LV s are mirrored with Strict mirror policy then data is somewhat safe, else take a data backup if possible.

this indicates more probably disk is failing or as said hot swap of a disk could have caused this
