adding a new disk

Ferdinand_5 — Thu, 30 Sep 2004 06:41:43 GMT

I'll have to add a new disk to a machine.

It is set up funny with lots of VG's
Here's my ioscan -fnCdisk:

can I just insf
then pvcreate /dev/rdsk/c0t9d0 ( number ok?)
vgextend vg07 /dev/dsk/c0t9t0
vgdisplay -v vg07

Am I right on this?

Re: adding a new disk

Pete Randall — Thu, 30 Sep 2004 06:59:53 GMT

That looks exactly right to me. The only thing to watch out for is that the PE size and Max PE for PV values are suitable to the size of the disk you're adding. If they are too small and this disk is larger than the original, you won't be able to use the whole disk. You would have to re-create the VG in that case.

Thanks Pete,

Is the /dev/rdsk/c0t9d0 number OK?
It is an old hp 9000 D220 and I was going to stick that new disk in the first available slot in the front ( which is the third slot )
underneath the two 9.1 GB disks already there.

Sยภเl Kย๓คг — Thu, 30 Sep 2004 07:23:01 GMT

Yes u can use /dev/rdsk/c0t9d0
#pvcreate /dev/rdsk/c0t9d0
#vgextend vg07 /dev/dsk/c0t9d0
will do

if you do:

# strings /etc/lvmtab this should show the active disks and which volume group they are assigned to.

Have you inserted the new drive yet? Do /dev/rdsk/c0t10t0 and /dev/rdsk/c0t9t0 show up in ioscan?

Your vgdisplay seems to show 5 active volume groups which occupy 5 physical drives. Unless you have some external storage attached, I would think you wouldn't have anywhere left to place new drives.

Re: adding a new disk

Ferdinand_5 — Thu, 30 Sep 2004 10:13:06 GMT

The new disks are inserted into the machine.
it has 5 slots in the front two of which were used.
The other disks are external.

I have issued a insf -e command

but my /dev/rdsk/

dir does not show any new files.

Also my ioscan -fnCdisk does not show my new disk "QÂ£$^Â£%^&

Re: adding a new disk

Pete Randall — Thu, 30 Sep 2004 10:16:42 GMT

I have to wonder if the drive is even compatible with the machine. Perhaps you should try loading the latest HWE patch bundle.

Pete

Re: adding a new disk

Ferdinand_5 — Thu, 30 Sep 2004 10:53:04 GMT

The new disks are the same.

I even rebooted the machine.

Can't see a thing on ioscan -fnCdisk.

Starting to panic....

Re: adding a new disk

Pete Randall — Thu, 30 Sep 2004 11:08:18 GMT

Double check all connections and terminations. That's about all I can think of at this point.

The D220 is not capable of having more then 2 hdd's in it's front slot.

So good thing i had one free slot in an external box.

Problem solved Thanks you all
