In my AIX 6.1 box the rootvg was on hdisk2, I tried to migrated it to hdisk0
Added hisk0 to rootvg , mirrored rootvg and changed bootlist and and sucessfully rebooted from hdisk0
Now I tried to remove the hdisk2 from rootvg so breaked mirror
Code:
-bash-3.00# unmirrorvg rootvg hdisk2
0516-1246 rmlvcopy: If hd5 is the boot logical volume, please run 'chpv -c <diskname>'
as root user to clear the boot record and avoid a potential boot
off an old boot image that may reside on the disk from which this
logical volume is moved/removed.
0516-1804 chvg: The quorum change takes effect immediately.
0516-1144 unmirrorvg: rootvg successfully unmirrored, user should perform
bosboot of system to reinitialize boot records. Then, user must modify
bootlist to just include: hdisk0.
-bash-3.00# bootinfo -b
hdisk0
-bash-3.00# chpv -c hdisk2
-bash-3.00# reducevg rootvg hdisk2
-bash-3.00# lspv
hdisk0 0005f8b2b7e6a0f7 rootvg active
hdisk1 0005f8b29b394a29 datavg active
hdisk2 0005f8b223e256a9 rootvg active
even after reducing the VG the hdisk2 still reflects in rootvg
Later I found that the Hdisk contained the sysdumplv
Code:
-bash-3.00# lspv -l hdisk2
hdisk2:
LV NAME LPs PPs DISTRIBUTION MOUNT POINT
lg_dumplv 12 12 00..12..00..00..00 N/A
I manually migrated the dumplv to hdisk0 and then removed the hdisk2 from rootvg sucessfully
Code:
-bash-3.00# reducevg rootvg hdisk2
-bash-3.00# lspv
hdisk0 0005f8b2b7e6a0f7 rootvg active
hdisk1 0005f8b29b394a29 datavg active
hdisk2 0005f8b223e256a9 None
I wonder why the mirroring didn't happened for the dumplv when i used mirrorvg rootvg as i saw the following before fixing the issue where the DUMP lv is not mirrored by mirrorvg command where rest all LV's got mirrored.
System dump devices should not be mirrored. You usually create 2 of them separate on each hdisk in your rootvg using smit or mklv. One will be your primary, the other the secondary.
Check out this link or check the man page of mirrorvg to read up on it:

in trying to rectify a stale lv problem I ran rmlvcopy <lv> 1 <primary disk> leaving the original os disk without lv copies other than the stale lv.

The end goal is to re-attach the lv's back to hdisk1, and then attempt a reboot... (11 Replies)

Hello,
Few days ago I created both mksysb and savevg archives of rootvg.
How can I restore this rootvg now because the AIX crashed during some software tests. There is no way to start from hdisk0 because most of the system files are deleted (this includes libc.a).
I tough it will be trivial... (6 Replies)
