% cfgadm -al |grep tape
This produces output lines with a format similar to the following:
c9::rmt/0
The rmt/K entry indicates the tape device file, where K is the instance number. In the above example,
rmt/0 indicates a set of device file options for one tape drive, such as /dev/rmt/0cb, /dev/rmt/
0cbn, and so on.
The cfgadm command may also be used with the v (verbose) option to list a full path including the
SAS controller:
% cfgadm -val |grep tape
An output containing, for example, "/devices/pci@0/pci@0/pci@8/pci@0/pci@1/
LSILogic,sas@0:scsi::rmt/1" indicates an SAS tape drive connected via an LSI SAS HBA.
Kernel patch levels
For optimal performance, ensure that you have the following minimum patch number:
Solaris 9
Solaris 10
Upgrading to the minimum patch level will ensure that the necessary support for officially supported
drives is included in the driver. You can view your existing patch level using the command "uname
-a". To access Solaris patch upgrades, you need to set up an Online Account with Sun to use
/www.sunsolve/sun/com/.
NOTE:
Patch levels are liable to change every 6 months or so, so these minimum" levels may quickly become
out-of-date.
To obtain the lastest levels, enter the patch names into the search utility Search the SunSolve
Knowledgebase" found on http://www.sunsolve/sun/com/.
If for some reason you cannot upgrade to the minimum patch level, you can make the following file
modifications to enhance performance:

Device file variants for a given tape device are listed in /dev/rmt with various suffixes—l, m, h, u, c specifying the 'density'
(low, medium, high, ultra, compressed), plus additional options b, 'Berkeley' behavior, and n, no rewind behaviour. HP
recommends the 'Berkeley' device file option for most applications with compressed density c: /dev/rmt/0cb or /dev/rmt/
