Re: Very slow restores (days), hours to locate files

Sorry about the omission, Rich.
These restores were started via the Windows GUI. I believe they just
selected the C: drive and specified "Restore if newer" (an option which I
don't think is available via the command line!). I believe this created a
No-Query Restore, because it did create a Restartable Restore.... AFAIK
there is a one-to-one correspondence (right?)
In the meantime, I checked the Technote... Then, I checked my Activity Log
for the last 24 hours... and I found 33 LTO volumes that presented the
cartridge memory message! So, now I have the smoking gun, and I suppose I
could do "move data" against those volumes, but I suspect there are many
more, and I would like to know what's causing the corruption and how to
prevent it! If I don't hear anything from the group, I'll open a call
with Tivoli.
Thanks very much for the information!

Please respond

Please, everyone, when posting questions about restorals, give
details about the manner in which the restoral was invoked so that we
can get a sense of what kind is involved (NQR, Classic) and what is
involved.
Now... Robin, have a look at IBM Technote 1209563, which I ran
across in doing research yesterday. I recall such long-duration-
restores in the past, and as I recall they have involved the factors
noted in the Technote. LTO is also known for backhitch delays, so
that's another contributor in positioning on tape.
