we replaced several 9GB disk drive with 36GB ones and now gain a lot of unallocated space. we decided to delete 7 LUNS ( total 8) and recrated LUNS with more space.
My question is if we create 5 lUNS now, would vgcfgrestore work? ( we already did vgcfgbacku)
All the original 7 LUNS go to /dev/vg02 which span about 14 logical drives from the original setup. Is it possible to let it span few?
Thanks.
# vgexport -v -m vg02map /dev/vg02
Beginning the export process on Volume Group "/dev/vg02".
/dev/dsk/c3t1d0
/dev/dsk/c3t1d1
/dev/dsk/c3t1d2
/dev/dsk/c3t1d3

/dev/dsk/c4t0d7
Volume group "/dev/vg02" has been successfully removed.
Solved! Go to Solution.

Re: 12H autoraid array space management
I hope you backed up everything beforehand because you only option is a restore of the data after build your new VG's and filesystems.

Re: 12H autoraid array space management
If this is the case, we need to do the pvcreate and vgcreate from the start. However, after recreating new LUNs,
ioscan -fnC disk show some problem NO_HW
disk 19 1/12/0/0.0.7 sdisk NO_HW DEVICE HP C5447A
/dev/dsk/c4t0d7 /dev/rdsk/c4t0d7

SolutionBy the way, you could probably do just as well with only 2 equally sized LUN's (One with primary path through controller X and the other with primary path through controller Y. You then stripe each LVOL in your VG across both LUN's in 64k chunks. This will fully utilize both external SCSI paths and all four internal SCSI paths.

Re: 12H autoraid array space management
we just reboot the server and those went away. We then did pvcreate on each one and then lvcreate, newfs. everything went well.
