AIX commands to find device information for Tivoli Storage Manager

Answer

A number of commands can be used to collect tape related information from an AIX host. The following list presents a small, but useful, subset of commands and a brief description of the information returned by each:

lsdev -Cc tape
Collects all special device file names created by successful installation of the IBM Tape device driver. For example:

# lsdev -Cc tape
rmt0     Available   06-01-02 IBM 3580 Ultrium Tape Drive (FCP)
rmt1     Available   06-01-02 IBM 3580 Ultrium Tape Drive (FCP)
smc0     Available   0A-01-02 IBM 3584 Library Medium Changer (FCP)

lscfg -vl rmt*
Collects each drive's serial number as recorded in the special device file. For example:

# lscfg -vl rmt*
  rmt0 U0.2-P1-I7/Q1-W50050763004F4B04-L0  IBM 3580 Ultrium Tape Drive (FCP)
 
        Manufacturer................IBM
        Machine Type and Model......ULT3580-TD4
        Serial Number...............1234567890
        Device Specific.(FW)........BBHA
 
  rmt1 U0.2-P1-I7/Q1-W50050763004F4B05-L0  IBM 3580 Ultrium Tape Drive (FCP)
 
        Manufacturer................IBM
        Machine Type and Model......ULT3580-TD4
        Serial Number...............1234567891
        Device Specific.(FW)........BBHA

lsattr -El rmtX
Collects the WWN as recorded in the special device file for the given device (e.g. 'rmt0'). For example:

# lsattr -El rmt0 | grep "ww_name"
ww_name   0x5005076300476407  World Wide Port Name        False


tapeutil -f /dev/smc0 devids
Collects each drive's element and serial number as reported by the library device. Note, tapeutil has recently been replaced by the IBM Tape Diagnostic Tool (ITDT), but the options are the same (e.g. itdt -f /dev/IBMchanger0 devids). More information about obtaining ITDT can be found here. For example:

# tapeutil -f /dev/smc0 devids
