netbackup 7.5 netapp lto6 drive issue

[j-iverson]

setting up a dr netbackup environment at another location.  both environments are similar, linux master/media, netbackup 7.5.0.6, adic/quantum tape library, ibm lto6 tape drives.  at the new site the netapp returns an incorrect "format:" from the "mt" command, says it is lto-4/5 instead of lto6, and i think because of this, the "tpconfig -dev_ping" also fails, and the storage unit cannot be used.  output from commands both local (works) and remote (broken) are:

houston netapp connected to lto6 device, looks good:

Failed to inquiry the specified device.

both netapps are at the same release: NetApp Release 8.2.2RC2 7-Mode.  we have 10 local netapps at various release levels and i have never had this problem.  both tape_config/IBM_LTO6_ULTRIUM.TCF files are the same are each filer.  options tape.reservations are both "off", i don't think we've ever had to play with these for 7-mode.

i was able to add the netapp to the drive in the device gui, and it saw the correct serial number, had me stop/restart the media manager services as usual.  it looks to be an issue on the netapp, but there is not much more there that i know to look into.  any suggestions?

thanks,

Whichis your actual problem, "tpconfig -dev_ping" failure for dallas8060 or difference in mt output?

It seem that any tape is not mounted when you ran mt, so format can be ignored I think.

For former problem, please try same option for dallas8060. "-drive" option is missed for dallas.

great catch on the missing "-drive" option.  my cut and paste from one terminal to the other must have missed it, and then i kept using command history to re-run it to the 2 netapps i was setting up.  also found a config error made by a fellow worker, so it is working now.  i guess the "format" area from the mt command doesn't matter.

thanks,
