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
