Changing The Ha Configuration Manually - HP StoreAll 8800 Administrator's Manual

backups. Using programmable power sources prevents a "split-brain scenario" between a failing
file serving node and its backup, allowing the failing server to be centrally powered down by the
Fusion Manager in the case of automated failover, and manually in the case of a forced manual
failover.
StoreAll software works with iLO, IPMI, OpenIPMI, and OpenIPMI2 integrated power sources.
The following configuration steps are required when setting up integrated power sources:
For automated failover, ensure that the Fusion Manager has LAN access to the power sources.
Install the environment and any drivers and utilities, as specified by the vendor documentation.
If you plan to protect access to the power sources, set up the UID and password to be used.
Use the following command to identify a power source:
ibrix_powersrc -a -t {ipmi|openipmi|openipmi2|ilo} -h HOSTNAME -I IPADDR
-u USERNAME -p PASSWORD
For example, to identify an iLO power source at IP address 192.168.3.170 for node ss01:
ibrix_powersrc -a -t ilo -h ss01 -I 192.168.3.170 -u Administrator -p
password
3. Configure NIC monitoring
NIC monitoring should be configured on user VIFs that will be used by NFS, SMB, FTP, or HTTP.
IMPORTANT:
configuring backup servers.
Identify the servers in a backup pair as NIC monitors for each other. Because the monitoring must
be declared in both directions, enter a separate command for each server in the pair.
ibrix_nic -m -h MONHOST -A DESTHOST/IFNAME
The following example sets up monitoring for NICs over bond0:1:
ibric_nic -m -h node1 -A node2/bond0:1
nl
ibric_nic -m -h node2 -A node1/bond0:1
nl
ibric_nic -m -h node3 -A node4/bond0:1
nl
ibric_nic -m -h node4 -A node3/bond0:1
nl
The next example sets up server s2.hp.com to monitor server s1.hp.com over user network interface
eth1:
ibrix_nic -m -h s2.hp.com -A s1.hp.com/eth1
4. Enable automated failover
Automated failover is turned off by default. When automated failover is turned on, the Fusion
Manager starts monitoring heartbeat messages from file serving nodes. You can turn automated
failover on and off for all file serving nodes or for selected nodes.
Turn on automated failover:
ibrix_server -m [-h SERVERNAME]

Changing the HA configuration manually

Update a power source:
If you change the IP address or password for a power source, you must update the configuration
database with the changes. The user name and password options are needed only for remotely
managed power sources. Include the -s option to have the Fusion Manager skip BMC.
ibrix_powersrc -m [-I IPADDR] [-u USERNAME] [-p PASSWORD]
The following command changes the IP address for power source ps1:
ibrix_powersrc -m -I 192.168.3.153 -h ps1

When configuring NIC monitoring, use the same backup pairs that you used when
