NOTE:
•
Verify that the root partition contains adequate free space for the upgrade. Approximately 4
GB is required.
•
Be sure to enable password-less access among the cluster nodes before starting the upgrade.
•
Do not change the active/passive Fusion Manager configuration during the upgrade.
•
Linux StoreAll clients must be upgraded to the 6.x release.
Upgrading 9720 chassis firmware
Before upgrading 9720 systems to StoreAll software 6.1, the 9720 chassis firmware must be at
version 4.0.0-13. If the firmware is not at this level, upgrade it before proceeding with the StoreAll
upgrade.
To upgrade the firmware, complete the following steps:
1.
Go to
http://www.hp.com/go/StoreAll
.
2.
On the HP StoreAll Storage page, select
HP Support & Drivers
from the
Support
section.
3.
On the Business Support Center, select
Download Drivers and Software
and then select
HP
9720 Base Rack
>
Red Hat Enterprise Linux 5 Server (x86-64)
.
4.
Click
HP 9720 Storage Chassis Firmware
version 4.0.0-13.
5.
Download the firmware and install it as described in the HP 9720 Network Storage System
4.0.0-13 Release Notes.
Online upgrades for StoreAll software 6.x to 6.1
Online upgrades are supported only from the StoreAll 6.x release. Upgrades from earlier StoreAll
releases must use the appropriate offline upgrade procedure.
When performing an online upgrade, note the following:
•
File systems remain mounted and client I/O continues during the upgrade.
•
The upgrade process takes approximately 45 minutes, regardless of the number of nodes.
•
The total I/O interruption per node IP is four minutes, allowing for a failover time of two minutes
and a failback time of two additional minutes.
•
Client I/O having a timeout of more than two minutes is supported.
Preparing for the upgrade
To prepare for the upgrade, complete the following steps:
1.
Ensure that all nodes are up and running. To determine the status of your cluster nodes, check
the dashboard on the GUI or use the
ibrix_health
command.
2.
Ensure that High Availability is enabled on each node in the cluster.
3.
Verify that
ssh
shared keys have been set up. To do this, run the following command on the
node hosting the active instance of the agile Fusion Manager:
ssh <server_name>
Repeat this command for each node in the cluster and verify that you are not prompted for a
password at any time.
4.
Ensure that no active tasks are running. Stop any active remote replication, data tiering, or
rebalancer tasks running on the cluster. (Use
ibrix_task -l
to list active tasks.) When the
upgrade is complete, you can start the tasks again.
5.
The 6.1 release requires that nodes hosting the agile management be registered on the cluster
network. Run the following command to verify that nodes hosting the agile Fusion Manager
have IP addresses on the cluster network:
ibrix_fm -f
If a node is configured on the user network, see
“Node is not registered with the cluster network
” (page 22)
for a workaround.
