Omni Back mma, lbin file

[carl_46]

I am trying to write a script that scans several tape drives to verify the external numbers match the internal ones. Doing this from the gui works well but of course can't be scripted. The commands it uses is "mma". everytime I try to capture the command with ps -ef, the comman gets cut off at the end because its too long. Does anyone know how i can see the entire command? or better yet does anyoneknow of the syntax that i could use with the mma command to scan a drive?
I know of the omnimlist command but the info it presents is too verbose.

Hi:

ps reports only a subset of the command line since only a limited amount is saved by the kernel; as much of the command line will be displayed as is available -- about 40-characters.

Hi, you can use the utility TapeAnalyser ie:

/opt/omni/sbin/utilns/TapeAnalyser -device /dev/rmt/#m -summary -header

You will get something like this:
=============== MEDIUM START BLOCK ===============
6e4e4253 41424344 0 0 0 0 0 MA_BLK_START MA_BLK_NULL 0 8192 236
medDateInitialized = Thu Nov 5 11:02:01 1998
medDateLastAccess = Thu Nov 5 11:02:01 1998
medDateLastWrite = Thu Nov 5 11:02:01 1998
medDateLastOverwrite = Thu Nov 5 11:02:01 1998
medNumWrites = 0
medNumOverwrites = 0
devInfoLength = 24
devInfoOffset = 288
medID = bf020402:36417799:34d5:0001
medLabel = NML0170
medLocation =
poolLabel = DLT7000
devCapacity = 0
medFmtVersion = 1

DEVICE INFO STRUCTURE:

devType = UNKNOWN
devBlkSize = 65536
woeStartPos = 0
woeEndPos = 0
segNum = 0
Number of blocks in the segment = 2

Of course if you have a library you have to insert the tape with ie. the uma(1M) utility.

Hi,

did you tried omnimm -media_info MEDIA?
Here you can see the internal Label called Medium ID (this is unique and is in hex) and the external Label called Medium Label. The external Label can be changed with the gui or with omnimm -modify_medium.
This command will read the catalogdb. If you have your tapes inside a lib you shoul rescan this before (omnimm -repository_barcode_scan or omnimm -repository_update) Take care if you don't have barcodes, the repository_update will take some time because it will rescan your complete lib.

If you have further question contact me.

Regards

Frank
