Add SDLT 220/320/600 tape drive support to MMS. [PSARC/2008/729 Self Review]

[Dean Roehrich]

I am sponsoring this case for Brian Kuyper.  I believe it qualifies for self
review and am marking it closed approved.  If anyone disagrees, let me know
and I will change it to a fasttrack.

The new mmsadm(1m) manpage is in the case directory.

Release binding is Minor.

4. Technical Description

Proposal:

	Add SDLT 220/320/600 tape drive support to MMS.

	The following CRs are used to track this case:
	6618271 RFE: Qualify SDLT 220/320 tape drives on SMMS
	6618272 RFE: Qualify SDLT 600 tape drive on SMMS

Details:

	MMS already supports a number of tape drives and this is a new device
	qualification.  The existing mmsadm(1m) CLI is already designed to
	have new devices added via its existing ``mediatype=type'' option.
	
        Every device type supported by MMS has its own device library.  This 
	change creates three device libraries for the SDLT 220, 320 and
	600 library by modifying the inquiry string and the density codes.

	The mmsadm command's mediatype option will be adjusted to allow the
	new device to be specified.

	The manpage's mediatype option will receive the following update:

	An example mmsadm command to specify the SDLT 600 will then be:

# mmsadm create -t voltype -o size=1000 -o mediatype=SDLT2 -l library1 -A ADM ABC123
		


Packaging:

	The new libraries will be added to the existing MMS library package,
	SUNWmmsu.
