Re: restore without missing tape

Alex,

If the tape is truly "bad", first audit that tape (audit vol xxx fix=yes);
if you just want to skip past that tape, one "trick" I've used is to force
classic restore -- nqr won't skip "unavailable" tapes, classic will (or it
used to in the v 3.1 timeframe)...

To force "classic" restore, specify the filespec with a trailing /?* (or
\?*);  you can verify classic restore is running by *not* getting the
message "waiting for files from the server..." (See the Tech. Guide for v
3.1, or Admin Guide, for other parameters that force classic restore
method).

BTW, another advantage to classic restore is it will minimize tape mounts on
the TSM server -- it sorts the eligible restore files/dirs by their needed
tape mounts before sending any data (and only sends data that meets the
restore spec's -- so there is much more "think time" before any data starts
to flow.)

If all this fails (to help), read the Admin Guide topic -- "Correcting
Damaged Files" (it's two pages long); if a file was marked "damaged", and
the data had been copy pool'ed, the (offsite?) copy pool tapes will be
requested; again, since they're unavailable, classic restore will list the
vol's being skipped (in the act-log) but still process data from the
"available" tapes.

Need more help?  Copy-and-paste the error msg you are receiving, include any
relevant context (and added messages that immediately precede or follow).

Subject: restore without missing tape


we've got adsm server 3.1 on an aix 4.3.3 machine. tape library is 3575.

if ive donw a restore of an entire filesystem, but the restore stopped due
to a tape error, and that tape is just totally dead (cant migrate anything
off of it), how do i continue the restore of other good data that isnt on
that bad tape.

i ask because im doing a restore of a 23GB filesystem, and it stopped at
7GB complaining about a bad tape. fine, but if i continue the process,
will it go on to other good tapes? or will it sit there and keep
complaining about that bad tape. how do i restore all the other good data
and avoid that bad tape?

thanks in advance!

alex
