hdisk1 errors

[harpal]

Hi,

I have noticed that our F80 has a problem with hdisk1 (rootvg) this needs to be swopped out I need advice on how best to plan for this in terms of removing old disk and installing new disk and keeping rootvg intact?

Any suggestions

also is this disk likely to go bang at any time ?

Is your rootvg mirrored?

If so I assume it's on hdisk0/1.

unmirrorvg rootvg hdisk1

reducevg rootvg hdisk1

rmdev -l hdisk1 -d

Replace the disk drive

cfgmgr

extendvg rootvg hdisk1

mirrorvg rootvg

make sure you have a newly created boot image

bosboot -ad /dev/hdisk1
bootlist -m normal hdisk0 hdisk1

Hi,

Thanks for your reply having a look @ hdisk0 and hdisk1 we do have mirroring but not @ at disk level but have certain logical volumes mirrored which might be a problem below is a lspv of both hdisk0 and hdisk1 and a lspv -l of hdisk0 and hdisk1

Many Thanks Harpal

Looks like you need to add a 3rd disk and move the lv off of hdisk1 that do not have a copy on hdisk0.

You don't have any space on hdisk0.

migratepv -l lv00 hdisk1 newhdiskN
migratepv -l lv01 hdisk1 newhdiskN

Or you could backup/restore on the new disk.

Thanks

I was looking more along the line of a exportvg of rootvg and then removing the hdisk1 and popping in a replacement and then importing rootvg back.

is this plasable.

Many Thanks

But harpal, from the output of lspv -l hdisk0 and lspv -l hdisk1 , I dont thin you have LV mirroring of any of the
logical volumes as both the oupt showns muber of LP equal to
number of PP. I think hdisk1 was intially mirrored but is no
more a part of any king of mirror.

theycallmetim is right that either you add another disk2
to rotvg and migrate LV from hdisk1 to hdisk2 and then
remove hdisk1 or take backup of LV on tape and then remove
th disk.

command exportvg should probably be called rmvg, don't do that without a backup.

The exportvg command removes all of the info about the disk from the system (ODM) but the data is still existent on the disk but can be moved to another machine where you run importvg and the info is added from the disk to the ODM on the new system.

It looks to be mirrored with the exception of /oracle and the 2 additional /usr/welcome* filesystems.

Whatever is on hdisk1 though is no longer in sync with hdisk0 because the partitions have been marked stale on hdisk1.

my bad ;-) not explaining properly. i blame lack of sleep.

exporting or removing rootvg would be a neat trick

 

[harpal]

hi,

guy's thanks for all your input I have a successful mksysb backup of the system which is about 2 weeks old, thinking the best solution maybe to remove the hdisk1 and pop new disk in and run a mksysb. does this sound ok any ideas on this one?

regards
