You still need to backup your data in these type of cases even though the documentations say you can do it online w/o losing data. Its A MUST. You should not take anything for granted.
Like these;;;
Bug 6258674 - You should not perform volume operations, such as volume resizing, until volume initialization is complete. The Sun StorageTek 6140 Array can hang if volume resizing operations are done before a volume is initialized.
Bug 6415976 - Volumes on expansion trays are failed by the controller when all access to the expansion tray is lost. A failed volume cannot be recovered even after power to the expansion tray is restored.
Dynamic reconfiguration -- Volume expansion, RAID migration, capacity expansion, segment size migration, volume/virtual disk reconfiguration, controller firmware upgrades
please do document your action plan. do post it for others to learn to, about your experience.
good luck!

Hello,
I have logical volume group of 50GB, in which I have 2 logical volumes, LogVol01 and LogVol02, both are of 10GB.
If I extend LogVol01 further by 10GB, then it keeps the extended copy after logical volume 2. I want to know where it keeps this information

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).
