Operating Systems AIX problem with lv Post 302215347 by zaxxon on Wednesday 16th of July 2008 06:23:59 AM

This happens, because when the VG and LVs were created, there was no restriction on which PVs they will go - ie. none selected it from smit or mkvg or mklv.
If none was selected, they take whatever hdisk has free space and is member of that VG.

Since there is no mirror (as you can see by the number of PPs which is the same amount for LPs) even parameters like
Quote:
EACH LP COPY ON A SEPARATE PV ?: yes
are not taken into account, since you have
Quote:
COPIES: 1
for each LV.

If you are using an internal raid controller or external raid disks for rootvg, all might be good. If not, I recommend strongly that you get a 4th or 5th and 6th disk (if the space is sufficient then) and start (AIX) mirroring all the LVs (lvcopy).
Else if you have a crash, you have to rely solely on your mksysb, after replacing defect disk(s).
After everything is mirrored, you will have to use "migratelp" to move each copy of an LP (PP) to another hdisk, so that the mirror makes sense in the end.

lvscan

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

NAME

       lvscan - scan (all disks) for Logical Volumes

SYNOPSIS

       lvscan [-a|--all] [-b|--blockdevice] [-d|--debug] [-h|--help] [--ignorelockingfailure] [-P|--partial] [-v|--verbose]

DESCRIPTION

       lvscan  scans all known volume groups or all supported LVM block devices in the system for defined Logical Volumes.  The output consists of
       one line for each Logical Volume indicating whether or not it is active, a snapshot or origin, the size of the device  and  its	allocation
       policy.	Use lvs(8) or lvdisplay(8) to obtain more-comprehensive information about the Logical Volumes.

OPTIONS

       See lvm for common options.

       --all  Include information in the output about internal Logical Volumes that are components of normally-accessible Logical Volumes, such as
	      mirrors, but which are not independently accessible (e.g. not mountable).  For example, after creating a mirror using 'lvcreate  -m1
	      --mirrorlog disk', this option will reveal three internal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.

       -b, --blockdevice
	      This option is now ignored.  Instead, use lvs(8) or lvdisplay(8) to obtain the device number.
