Hi,
I'm new to HP-UX.
I have LVM on /var with 92Gig. I would like to reduce it to create another LVM for Oracle client with 800 meg or so. How to do it. I'm running 11.iv3

Please consider this a question about basics&best practices. On AIX 5.3 system, three raw physical volumes are defined from storage. While doing a read with command dd from the raw device, the speed rate is 250Mb/s.
Then, it gets complex when I define these three pv's to an lv of type raw. Doing... (4 Replies)
Is there a trick to mounting swap in n a lvm? I can't get it to work.
# swapon -va

Good morning
Recently we needed to change the password from a redhat 6.5 system that no one knew the root password.
Starting the system with the init=/bin/bash method took us to the following scenario:
system_vg active with only root_lv and tmpfs mounted.
our entries at fstab are like... (1 Reply)
Currently I am using this laborious command
lvdisplay | awk '/LV Path/ {p=$3} /LV Name/ {n=$3} /VG Name/ {v=$3} /Block device/ {d=$3; sub(".*:", "/dev/dm-", d); printf "%s\t%s\t%s\n", p, "/dev/mapper/"v"-"n, d}'
Would like to know if there is any shorter method to get this mapping of... (2 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).
