In the case of failure of both the master node and the standby node, the cluster continues to operate
by electing a new master from the list of available nodes.

SAN Gateways, as well as the boot images. Two boot images are installed for each SAN Gateway,
each in a separate partition.
To view the software version and choose a boot image, do the following:
1. Select Administration > Cluster Admin > Reboot.
2. To view the version of software running on the SAN Gateway, look at the Software Version
section of the Software panel.
3. To view the installed boot images, look at the Installed Images section of the Software panel.
Rebooting or Shutting Down a Node
You can reboot or shut down a SAN Gateway node through the HP VMA Web Interface.
• Shutdown—Stops a SAN Gateway node or removes the node from the SAN Gateway cluster
for planned maintenance or upgrade.
• Reboot—Restarts a SAN Gateway node, clearing its data but retaining the existing
configuration settings. In a cluster, the standby SAN Gateway takes over while the previously
active master node reboots.
Caution: Rebooting a SAN Gateway node may cause a temporary decline in overall performance.
To reboot or shut down a SAN Gateway node, do the following:
1. Select Administration > Cluster Admin > Reboot.
The Cluster Administration page displays information on the current software version, the
installed software image, and configuration files. Two boot images are installed for each SAN
Gateway in separate partitions.
