New Tape Drives

[jjjon]

I have no Solaris experience whatsoever, so could someone tell me how I rescan to pick up new Tape Drives? These are fibre tape drives on a SAN and have all been zoned in already.
And what should I be looking for after the rescan?

Thanks

Jon

You can run "devfsadm -c tape" to assign newly attached taped drives. Look in /dev/rmt to see what you have available.

Thanks. I've run the devvfsadm command, and the /dev/rmt has lots of files in it now. Files start with 0,1,2 or 3 - I assume these reference each of the 4 drives - doesn't make much sense to me to be honest.

If it made sense we would all be out of a job!

Hi Jon. The 0,1,2 and 3 probably are references to your drives. You probably have versions like 0c, 0cn, 1c, 1cn etc too? These indicate (c) the 'compress' version of the tape (ie one which allows data compression, increasing the capacity of the tape) and a 'no-rewind' device so that the tape stops at the end of a save to allow for multiple saves to the same tape. So /dev/rmt/0cn is a compressed-no-rewind version of the standard 0 device. Note that the default (0, say) is for rewind, ie your tape will rewind when finished, running the risk of overwriting if you are wanting multiple saves on the one tape. There are also various tape manupulation options - man mt for details.

Any specific queries, post back here or in Forum60

Good luck.
