[ADSM-L] NDMP - TOC? upgrade?
2012-05-17 13:11:42
Environment: AIX 6.1, TSM 5.5.4
We've been backing up a couple of NAS filers via NDMP for around 18 months but
recently find that sending the data to a storage pool of 12 500G rlv-formatted
disks has been diagnosed by L2 as the cause of occasional problems with the
recovery log when it changes volumes -- holding the recovery log too long and
crashing the instance.
The rlv disk data has been moved off in preparation to rebuild the disks as
FILE devclass volumes...but think I remember reading something about TOCs being
troublesome/incompatible with that config? Since one of these NAS boxes has
millions (literally, I'm told) of small documents -- versions of which are
required to be kept forever -- TOC is a a 'must-have' for file level restore,
else we would have to restore the whole filesystem, the largest of which has
about 5-6TB in use.
Is anyone using NDMP writing to file devclass with TOC successfully? (any
suggestions on MAXCAP? default is 4M which seems 'small')
Side issue: think I heard there's no data export upgrade path for NDMP...'take
a fresh full backup' isn't going to work for millions of keep-forever
documents...we are planning to move to AIX 7.1 and TSM 6.2.x later this year
when the new hardware arrives so this will be upon us soon. Any comments/ideas?
Thanks, Susie
