Hello,
I need explanations about physical disks and physical volumes. What is the difference between these 2 things?
In fact, i am trying to understand what the AIX lspv2command does.
Thank you in advance. (2 Replies)
I was in smit, checking on disc space, etc. and it appears that one of our physical volumes that is part of a large volume group, has no free physical partitions. The server is running AIX 5.1. What would be the advisable step to take in this instance? (9 Replies)

Hi!
Can anyone help me on how I can do a basic check on the Unix filesystems / physical volumes and logical volumes?
What items should I check, like where do I look at in smit? Or are there commands that I should execute?
I need to do this as I was informed by IBM that there seems to be... (1 Reply)
I have a Sun T5120, and I want to programmatically determine how much RAM it has.

Hi,
I am new to unix. I am working on Red Hat Linux and side by side on AIX also. After reading the concepts of Storage, I am now really confused regarding the terminologies
1)Physical Volume

4)Physical Partition
Please help me to understand these concepts. (6 Replies)
I wanted to know how we can combine volumes over 2 physical drives.

Hello everyone,
I just read that while creating a logical volume(LV) we can choose the region of the physical volume (PV) in which the LV should be created.
When I say region I mean: outer edge - outer middle - center - inner middle and inner edge.
Can anyone help me understand the utility... (11 Replies)

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).
