An easy step:

# mklvcopy lvoracle 2 [hdiskX] ## Usage: /usr/sbin/syncvg [-i] [-f] [-H] [-P NumParalleLPs] {-l|-p|-v} Name # syncvg -l lvoracle

To make a new partition with two copies (i.e. mirrored) to start with - and perhaps as jfs2 rather than the default jfs (for mklv) - the following commands
# mklv -c 2 -y lvMyNewLV -t jfs2 vgOther 4G # makes a 4G partition in vgOther # crfs -v jfs2 -d lvMyNewLV -m /myNewFS [-A yes] # autotmount yes or no (default) # mount /myNewFS

couple of questions concerning mirroring

« on: November 28, 2007, 09:42:11 AM »

Hello,

I have a couple of questions concerning the mirroring process with AIX. I'm still investigating but I think this place is the best to ask so...

I followed this procedure to mirror the rootvg:
http://www.ibm.com/developerworks/aix/library/au-aixsolaris/index.html#list12

After a while I created a new file system /oracle. And I guess it is not automatically mirrored (my understanding of the column PVs).

lsvg -l rootvg
rootvg:
LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT
hd5 boot 1 2 2 closed/syncd N/A
hd6 paging 16 32 2 open/syncd N/A
hd8 jfs2log 1 2 2 open/syncd N/A
hd4 jfs2 1 2 2 open/syncd /
hd2 jfs2 24 48 2 open/syncd /usr
hd9var jfs2 8 16 2 open/syncd /var
hd3 jfs2 12 24 2 open/syncd /tmp
hd1 jfs2 160 320 2 open/syncd /home
hd10opt jfs2 20 40 2 open/syncd /opt
fwdump jfs2 1 2 2 open/syncd /var/adm/ras/platform
lvoracle jfs2 20 20 1 open/syncd /oracle

lspv -l hdisk0
hdisk0:
LV NAME LPs PPs DISTRIBUTION MOUNT POINT
hd8 1 1 00..00..01..00..00 N/A
hd6 16 16 14..02..00..00..00 N/A
hd2 24 24 00..14..06..04..00 /usr
hd4 1 1 00..00..01..00..00 /
hd3 12 12 00..11..01..00..00 /tmp
hd9var 8 8 00..07..01..00..00 /var
hd10opt 20 20 00..12..01..07..00 /opt
hd1 160 160 00..62..98..00..00 /home
hd5 1 1 01..00..00..00..00 N/A
fwdump 1 1 00..01..00..00..00 /var/adm/ras/platform

lspv -l hdisk1
hdisk1:
LV NAME LPs PPs DISTRIBUTION MOUNT POINT
hd8 1 1 00..00..01..00..00 N/A
hd6 16 16 00..16..00..00..00 N/A
hd2 24 24 00..04..20..00..00 /usr
hd4 1 1 00..00..01..00..00 /
hd3 12 12 00..00..12..00..00 /tmp
hd9var 8 8 00..00..08..00..00 /var
hd10opt 20 20 00..20..00..00..00 /opt
hd1 160 160 00..00..67..93..00 /home
hd5 1 1 01..00..00..00..00 N/A
lvoracle 20 20 00..20..00..00..00 /oracle
fwdump 1 1 00..01..00..00..00 /var/adm/ras/platform

How can I mirror /oracle? With syncvg?
How can you check mirror health too?

Than you for your help.
