6.0 HP X9720 Network Storage System Administrator Guide (AW549-96034, December 2011)

1. Power on the 9100cx disk capacity block(s).
2. Power on the 9100c controllers.
3. Wait for all controllers to report “on” in the 7-segment display.
4. Power on the file serving nodes.
Powering on after a power failure
If a power failure occurred, all of the hardware will power on at once when the power is restored.
The file serving nodes will boot before the storage is available, preventing file systems from
mounting. To correct this situation, wait until all controllers report “on” in the 7-segment display
and then reboot the file serving nodes. The file systems should then mount automatically.
Starting the X9000 Software
To start the X9000 Software, complete the following steps:
1. Power on the dedicated Management Console or the node hosting the active agile management
console.
2. Power on the file serving nodes (*root segment = segment 1; power on owner first, if possible).
3. Monitor the nodes on the management console and wait for them all to report UP in the output
from the following command:
ibrix_server -l
4. Mount file systems and verify their content. Run the following command on the Management
Console or file serving node hosting the active agile management console:
ibrix_mount -f fs_name -m <mountpoint>
On Linux X9000 clients, run the following command:
ibrix_lwmount -f fsname -m <mountpoint>
5. Enable HA on the file serving nodes. Run the following command on the Management Console
or file serving node hosting the active agile management console:
ibrix_server -m
6. On the node hosting the passive agile management console, move the console back to passive
mode:
ibrix_fm -m passive
The X9000 Software is now available, and you can now access your file systems.
Powering file serving nodes on or off
When file serving nodes are connected to properly configured power sources, the nodes can be
powered on or off or can be reset remotely. To prevent interruption of service, set up standbys for
the nodes (see “Configuring standby pairs” (page 30)), and then manually fail them over before
powering them off (see “Manually failing over a file serving node” (page 31)). Remotely powering
off a file serving node does not trigger failover.
To power on, power off, or reset a file serving node, use the following command:
<installdirectory>/bin/ibrix_server -P {on|reset|off} -h HOSTNAME
Performing a rolling reboot
The rolling reboot procedure allows you to reboot all file serving nodes in the cluster while the
cluster remains online. Before beginning the procedure, ensure that each file serving node has a
backup node and that X9000 HA is enabled. See “Configuring virtual interfaces for client access”
(page 25) and “Cluster high availability” (page 29) for more information about creating standby
backup pairs, where each server in a pair is the standby for the other.
