Title: couple of questions concerning mirroring Post by: lord taki 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. Title: Re: couple of questions concerning mirroring Post by: Michael on November 28, 2007, 02:26:15 PM 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 Title: Re: couple of questions concerning mirroring Post by: lord taki on November 28, 2007, 02:49:31 PM Thank you for the help.
It worked perfectly. |
