Locating Space from SAN (va7110)

[Mutum]

Our DBA ask to provide him with 150GB space to implement test instance, to do this I have to remove to old instances (volumes), those two volumes are on two different server as:

/dev/vg01/lvol11 97 GB mounted as /test this on my SVR1 server and it's a located from VA7110 SAN.
and :
/dev/vg00/lvol9 99GB this is on my svr2 server, it's on the server local disk.

both spaces are vxfs file system.

I want to join the two volumes so as to provide my dba with the required space.

Appreciate if some guide/advice me, as i'm new to HP-UX.I have HP-UX11iv1

Muatasim,

It is not possible to combine the spac from /lvol1 and /lvol9 as both the logical volumes are on different Volume group.

Can you please post the output of vgdisplay -v /dev/vg01.

Thanks Naveej,

Can I remove both of them, reducing the vg's and then create new one ?

Hi,

If you are not using both /vg01/lvol11 and /vg01/lvol2, then you can add c2t1d0 and /dev/dsk/c4t0d1 to VG00 so that you can use the free space available in VG01/lvol9 as well. The disadvantage is that VG00 will not get activated (and system won't boot) if LUNs from VA7110 are not accessible.

1. Unmount filesystems. (corresponding to lvol11 and lvol2)
2. vgexport /dev/vg01
3. pvcreate -f /dev/rdsk/c2t1d0

5. vgextend /dev/vg00 /dev/dsk/c2t1d0
6. lvextend -L 150000 -n /dev/vg01/lvol9
7. Umount the filesystem mounted on /vg00/lvol9
8. extendfs -F vxfs /dev/vg01/rlvol9
9. mount the filesystem corresponding to lvol9

With best wishes,
Naveej

Again thanks Naveej,

Unfortionatley still I need the file system on lvol12.

Whay u advice me to use pvcreate -f /dev/rdsk/c2t1d0 and not /dev/dsk/c4t0d1

On lvo12 ihave the following:

#/export>ls
lost+found srt
#/export>cd srt
#/export/srt>ls
hp11i
#/export/srt>

I don't know to remove it or not !!

I'm not sure why the previous system admin is uing it for wahat, may for Bare metal Restore.

Hi,

du -k /export

Can you back it up and then later copy it back.

backup /export
1. Unmount filesystems. (corresponding to lvol11 and lvol2)
2. vgexport /dev/vg01
3. pvcreate -f /dev/rdsk/c2t1d0
pvcreate -f /dev/rdsk/c4t0d1
5. vgextend /dev/vg00 /dev/dsk/c2t1d0
6. lvextend -L 150000 -n /dev/vg01/lvol9
7. Umount the filesystem mounted on /vg00/lvol9
8. extendfs -F vxfs /dev/vg01/rlvol9
9. mount the filesystem corresponding to lvol9
mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x010000
vgcreate vg01 /dev/dsk/c4t0d1
lvcreate -L 2000 -n lvol2 /dev/vg01
newfs -F vxfs /dev/vg01/lvol2
mount /dev/vg01/lv0l2 /export
then restore the backup
