6.3 HP StoreAll 9300/9320 Storage Administrator Guide (AW549-96072, June 2013)

Starting the StoreAll software
To start the StoreAll software, complete the following steps:
1. Power on the node hosting the active Fusion Manager.
2. Power on the file serving nodes (*root segment = segment 1; power on owner first, if possible).
3. Monitor the nodes on the GUI 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 file serving
node hosting the active Fusion Manager:
ibrix_mount -f fs_name -m <mountpoint>
On Linux StoreAll 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 file serving node
hosting the active Fusion Manager:
ibrix_server -m
6. From the active Fusion Manager, enter the following command to move all Fusion Managers
into passive mode:
ibrix_fm -m passive -A
The StoreAll 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 High Availability on the cluster” (page 53), and then manually fail
them over before powering them off (see “Failing a server over manually” (page 63)). 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:
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 StoreAll HA is enabled. See “Configuring virtual interfaces for client access”
(page 47) and “Configuring High Availability on the cluster” (page 53) for more information about
creating standby backup pairs, where each server in a pair is the standby for the other.
Use one of the following schemes for the reboot:
• Reboot the file serving nodes one-at-a-time.
• Divide the file serving nodes into two groups, with the nodes in the first group having backups
in the second group, and the nodes in the second group having backups in the first group.
You can then reboot one group at-a-time.
