to UP the drives try vmoprcmd command like this

vmoprcmd  -upbyname IBM.ULTRIUM-HH5.001  -path /dev/nst0

and

vmoprcmd  -upbyname IBM.ULTRIUM-HH5.003  -path nrst1a  -nh miafile03

[Pablo_Stani]

Thanks,

I am using the below commands:

tpconfig -d
vmoprcmd -UP <tape #>

I have also find that most of the tape issues are related to NDMP policies connected to a NetApp filers.

the policies are 2 pass backups so they go from the filers straight to the tapes and I am still looking the reason why they are going down.

[Amol_Nair]

run the "tpautoconf -probe " command from the media server to check if all the ndmp drives r correctly listed.. you would also need to involve your filer admin to check the logs on the filer side and also to ensure that there is no intermittent connectivity issue between the Ndmp filer and the tape library.

[Marianne · Accepted solution]

Something wrong with device access between OS and tape drives : "Invalid request type in ProcessQueue (0) ... timed out after waiting 854 seconds for ready, drive 8" These errors look like there had been at least 3 I/O errors in the last 12 hours for this drive: "Operator/EMM server has DOWN'ed drive" You should involve SAN and OS team to troubleshoot. I suspect there are other errors in messages file and that you only posted snippets, right?
