Hello Justin,
=20
If you are using an ACS library you have to turn off the use of tape =
alert flag. We had problems with the library hanging up, and found a =
veritas tech note that called for turning off cleaning of the tape =
drives with netbackup. The library handles the task.=20
=20
We also have an IBM 3584 library with the ALMS feature, and this calls =
for controlling the cleaning of tape drives by the library and not =
netbackup.=20

Subject: [Veritas-bu] No response concerning tape alert?
Anyone have any response to this e-mail concerning the tape alert flag?
=20
Hi,
=20
I have recently moved to new environment, which actively uses the tape =
alert setting in Veritas and has cleaning tapes assigned etc.
The drives used are HP-Ultrium2-LTO2, the same in the previous =
environment, which I was responsible for.
=20
As I recall in the NetBackup with LTO2 drives I read somewhere or a =
previous thread on this mailing list, it is not recommended to turn this =
feature on as it causes more probolems than it fixes? Can using the =
TapeAlert settings cause more drives to go down than normal?=20
=20
I am trying to figure that part out as my previous main environment had =
8 LTO2 drives which did not use tapealert.
=20
The new environment has many more drives but they all use tape alert, =
does anyone have any experience in large or small environments using =
tape alert? I've always seen and followed the standard placing the =
NO_TAPE_ALERT file in /usr/openv/volmgr/somewhere as it had never run in =
the past in the previous environment so I saw no reason to run it. I =
realize the drives will get dirty after a certain amount of use and need =
to be cleaned. However, I have spoken with StorageTek in the past and =
they do not recommend cleaning the drives very often; although I guess =
that would depend on the use the drives see as well.=20
=20
Ultimately, I'd like to know:
=20
1) Who uses tape alert?
2) Have you tried backups for an extended period of time with it on and =
off?
3) Does it create more problems than it fixes?
=20
Thanks,
