Gabconfig manual seeding

To enable GAB auto-seeding parameter of I/O fencing. Set the value of the autoseed_gab_timeout parameter in the /etc/vxfenmode file to 0 to turn on the feature. To delay the GAB auto-seed feature, you can also set a value greater than zero. GAB uses this value to delay auto-seed of the cluster for the given number of seconds.  · The GAB driver is dependent on the. prior to running gabconfig. -a Display GAB driver port memberships. -b Enable system halt when process heartbeat failed. process by default. When this option is used, GAB. halts the system. -c Configure the driver for use. Configuring the GAB. The main purpose of LLT is to transmit heartbeats. – GAB determines the state of a node with the heartbeats sent over the LLTs. – LLTs are also used to distribute the inter system communication traffic equally among all the interconnects. – We can configure upto 8 .

C:\Program Files\VERITAS\comms\llt\www.doorway.ru The commands to start and stop GAB are: # gabconfig -c (start GAB) # gabconfig -U (stop GAB) How to start/stop LLT What's a GAB seeding and why manual GAB seeding is required? The GAB configuration file /etc/gabtab defines the minimum number of nodes that must be communicating for the cluster to start. This is called as GAB seeding. Manual GAB membership seeding. It is possible that one of the nodes does not come up when all the nodes in the cluster are restarted, due to the "minimum seed requirement" safety that is enforced by GAB. Run the following command to manually seed GAB membership: # gabconfig -cx. Refer to gabconfig (1M) for more details. Prev: Up: Next.

Close the seed control port (port a) if all client ports are closed. -U Unconfigure the GAB driver and reinitialize all configuration states, including disk and seed configurations. -v Display GAB version information like the product version, build time stamp, interface version, minimum, maximum, and on-the-wire protocol versions. -x Seed. Manual GAB membership seeding. It is possible that one of the nodes does not come up when all the nodes in the cluster are restarted, due to the "minimum seed requirement" safety that is enforced by GAB. Human intervention is needed to safely determine that the other node is in fact not participating in its own mini-cluster. To manually seed the cluster, type the following command: /sbin/gabconfig -x. Note there is no declaration of the number of systems in the cluster with a manual seed. This command will seed all systems in communication with the system where the command is run. So, make sure not to run this command in more than one node in the cluster.
