Problem
How can LLT and GAB manually be unloaded and loaded on IBM AIX ?
Solution
Steps to stop and unload Global Atomic Broadcast (GAB)
1. Check if GAB is loaded:
# /usr/sbin/lsdev -CHc gab
name status location description
gab Available N/A
2. Check if GAB is running:
# /sbin/gabconfig -l
GAB Driver Configuration
Driver state : ConfiguredPartition arbitration: Disabled
Control port seed : Enabled
Halt on process death: Disabled
Missed heartbeat halt: Disabled
Halt on rejoin : Disabled
Keep on killing : Disabled
Restart : Disabled
Node count : 0
Disk HB interval (ms): 1000
Disk HB miss count : 4
IOFENCE timeout (ms) : 15000
Stable timeout (ms) : 5000
3. Stop GAB and verify:
# /sbin/gabconfig -U
# /sbin/gabconfig -l
GAB Driver Configuration
Driver state : UnconfiguredPartition arbitration: Disabled
Control port seed : Disabled
Halt on process death: Disabled
Missed heartbeat halt: Disabled
Halt on rejoin : Disabled
Keep on killing : Disabled
Restart : Disabled
Node count : 0
Disk HB interval (ms): 1000
Disk HB miss count : 4
IOFENCE timeout (ms) : 15000
Stable timeout (ms) : 5000
4. Unload GAB and verify:
# /usr/sbin/rmdev -l gab
gab Defined
# /usr/sbin/lsdev -CHc gab
name status location description
gab Defined N/A
Steps to stop and unload Low Latency Transport (LLT)
1. Check if LLT is loaded:
# /usr/sbin/strload -q -d llt
llt: yes
2. Check if LLT is running:
# /sbin/lltconfig
LLT is running
3. Stop LLT and verify:
# /sbin/lltconfig -U
lltconfig: this will attempt to stop and reset LLT. Confirm (y/n)? y
# /sbin/lltconfig
LLT is not running
4. Unload LLT and verify:
# /usr/sbin/strload -u -d llt
# /usr/sbin/strload -q -d llt
llt: no
Steps to load and start LLT (provided LLT is not loaded)
1. Load LLT and verify:
# /usr/sbin/strload -d llt
# /usr/sbin/strload -q -d llt
llt: yes
2. Start LLT and verify:
# /sbin/lltconfig -c
# /sbin/lltconfig
LLT is running
Steps to load and start GAB (provided GAB is not loaded)
1.Load GAB and verify:
# /usr/sbin/mkdev -l gab
gab Available
# /usr/sbin/lsdev -CHc gab
name status location description
gab Available N/A
2. Start GAB and verify:
# /sbin/gabconfig -c
# /sbin/gabconfig -l
