Table 4 IBM AIX timeout settings
Description
Value
Setting
Sets the key value for persistent reservations. Persistent reservations are not
supported.
NA
PR_key_value
Sets the load balancing algorithm to fail_over. All I/O uses a single path.
The remaining paths are in standby mode. The value round_robin is not
supported.
fail_over
Algorithm
Sets the path health feature to check each device every 60 seconds.
60
hcheck_interval
Specifies the I/O paths monitored by the path health checking feature:
nonactive—Checks all I/O paths for Failed status, and checks standby paths
for Used/Opened devices.
nonactive
hcheck_mode
Sets the queue depth.
8
queue_depth
Sets the reserve policy to standard SCSI-2 reservations.
Single path
reserve_policy
Sets the read/write timeout to 60 seconds.
60
rw_timeout
