Re: Optical Drives
the drive you point is supported but not directly. The the device you point
is actually re-writable CD recorder which can be thought similar to WORM
device (but is not the same). This kind of media IS supported in TSM
through REMOVABLE FILE device class :
"When you use CD-ROM media for the REMOVABLEFILE device type, the library
type must be MANUAL. You access the media through a mount point, for
example, /dev/cdx, where x is a number that is assigned by your operating
system. Use the device manufacturer's operating system utilities to format
(if necessary) and label the media. "
So after a file (in file pool) creation AND fill up you can write it to a
CD using scripts and tools like mkisofs+cdrecord. I do not know about
Solaris but those work on AIX.
I can recommend this to be used only for copy pools leaving you with two
choices - too many disks for primary pool or again good (old) tapes.
IMHO this device class is good to be used for backupsets and maybe DB

Subject: Optical Drives
I have been given the task of evaluating whether or not TSM is the
appropriate vehicle for long term archiving. As part of this process I
plan on installing the latest version of TSM on Solaris 8. I am
interested in which type of optical drive you may be using. I will not be
testing optical libraries, just a drive. I have reviewed the list of
supported devices and I am surprised by the lack of support beyond a few
(4) manufacturers. I was thinking of using the Plextor 12/10/32S External
SCSI CD-RW drive but it is not supported.
As part of the testing I was planning on determining whether or
not the data I write using TSM requires a TSM server or client to
recover. Obviously if the data has to be retained for any great length of
time I would prefer to avoid any proprietary formats.
If you have a TSM/Solaris environment with Optical devices, I am
interested in hearing your experiences.
