If you need to know what the acceptable values for device attributes are in AIX you can use the following.
For example,
My hdisk5 attributes can be listed with
# lsattr -El hdisk5 PCM PCM/friend/vscsi Path Control Module False algorithm fail_over Algorithm True hcheck_cmd test_unit_rdy Health Check Command True hcheck_interval 0 Health Check Interval True hcheck_mode nonactive Health Check Mode True max_transfer 0x40000 Maximum TRANSFER Size True pvid 000812ca6370c0140000000000000000 Physical volume identifier False queue_depth 3 Queue DEPTH True reserve_policy no_reserve Reserve Policy True |
But what if I want to know which values are acceptable for the reserve_policy attribute, for example?
In this case I can use
# lsattr -Rl hdisk5 -a reserve_policy no_reserve single_path |
Another example is
# lsattr -Rl hdisk5 -a queue_depth 1...256 (+1) |
