Hi,

Thank you both, now I can see mirrored LVs.

More information :
root> lslv -m lv01 |head
lv01:/data
LP PP1 PV1 PP2 PV2 PP3 PV3
0001 0111 hdisk2 0300 hdisk8
0002 0112 hdisk2 0110 hdisk9
0003 0113 hdisk2 0111 hdisk4
0004 0114 hdisk2 0292 hdisk3
0005 0115 hdisk2 0292 hdisk5
0006 0116 hdisk2 0301 hdisk8
0007 0117 hdisk2 0111 hdisk9
0008 0118 hdisk2 0112 hdisk4

(there are 900 lines of these).

So I can see this lv is mirrored, thanks!

It works for the lspv command too:
> lspv -M hdisk1|head
hdisk1:1 hd5:1:1
hdisk1:2-15
hdisk1:16 bpslv:186:1
hdisk1:17 bpslv:187:1
hdisk1:18 bpslv:188:1
hdisk1:19 bpslv:189:1
hdisk1:20 bpslv:190:1
hdisk1:21 bpslv:191:1
hdisk1:22 bpslv:192:1
hdisk1:23 bpslv:193:1

> lspv -M hdisk0|head
hdisk0:1 hd5:1:2
hdisk0:2-37
hdisk0:38 bpslv:186:2
hdisk0:39 bpslv:187:2
hdisk0:40 bpslv:188:2
hdisk0:41 bpslv:189:2
hdisk0:42 bpslv:190:2
hdisk0:43 bpslv:191:2
hdisk0:44 bpslv:192:2
hdisk0:45 bpslv:193:2

The last column is the "Copynum" (Mirror number), which indicates I guess that here hdisk0 and hdisk1 are mirrored.

However, the command lsvg does not seem to have such a way to see mirrored VGs. That's strange, because in the man of syncvg, it says "The syncvg command can be used with logical volumes, physical volumes, or volume groups (...)".

So now it seems I can get (painfully) most of the information I am looking for.

However, I am wondering if there is a graphical tool to "see" in a more user friendly way all the information linked to hd, pv, vg, lv, etc.
I googled for such a tool, but I probably did no put the correct keywords to find it.
Even if I do like command line, sometimes it is good to have a graphical way to present information.

Thanks
Yann

rootvg mirrored

I want to increase the size of /tmp by 1GB I know that the command is chfs -a size=+1G /tmp But the rootvg is mirrored and when I do a lsvg -p rootvg, I could see 2 disks. Will there be any impact if I increase the size of /tmp when the rootvg is mirrored ? Please advise.

vgreduce

VGREDUCE(8)						      System Manager's Manual						       VGREDUCE(8)

NAME

       vgreduce - reduce a volume group

SYNOPSIS

       vgreduce  [-a|--all] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--removemissing] [-t|--test] [-v|--verbose] VolumeGroupName [Physi-
       calVolumePath...]

DESCRIPTION

       vgreduce allows you to remove one or more unused physical volumes from a volume group.

OPTIONS

       See lvm for common options.

       -a, --all
	      Removes all empty physical volumes if none are given on command line.

       --removemissing
	      Removes all missing physical volumes from the volume group, if there are no logical volumes allocated on those. This resumes  normal
	      operation of the volume group (new logical volumes may again be created, changed and so on).

	      If this is not possible (there are logical volumes referencing the missing physical volumes) and you cannot or do not want to remove
	      them manually, you can run this option with --force to have vgreduce remove any partial LVs.

	      Any logical volumes and dependent snapshots that were partly on the missing disks get removed completely. This includes those  parts
	      that lie on disks that are still present.

	      If your logical volumes spanned several disks including the ones that are lost, you might want to try to salvage data first by acti-
	      vating your logical volumes with --partial as described in lvm (8).
