AIX – Some tape commands

Getting information about the tape drive.

root@aix:/ # lscfg -vpl rmt0

Device Specific.(Z3)……..L1
PLATFORM SPECIFIC
Name:  st
Device Type:  byte

Getting information about the tape. It is using compression and a variable length block size.

root@aix:/ # tctl -f /dev/rmt0 status
rmt0 Available 06-08-01-0,0 4.0 GB 4mm Tape Drive
ttribute  value description                          user_settable
block_size 0     BLOCK size (0=variable length)       True
compress   yes   Use data COMPRESSION                 True
mode       yes   Use DEVICE BUFFERS during writes     True
ret_error  no    RETURN error on tape change or reset True

Rewinding tape drive

root@aix:/ # tctl -f /dev/rmt0 rewind

Reading tape and redirecting output to a file. In this case, the operating system showed that the tape itself is damaged.

root@aix:/ # tctl -f /dev/rmt0 read > /tmp/testtape
tctl: 0511-578 Cannot read 512 bytes: The media surface is damaged.
