You can update the entire system in a coordinated process
with no user intervention after the update is initiated.
Follow these steps to update to version
8.1.0 or later from version 7.7.0 or later.
For the most recent information about restrictions before you update, see the
following site:
Before you update your system, review all of the
topics in
Updating to understand how the process
works.
Allow adequate time, such as up to a
week in some cases to look for potential problems or known bugs.Additional information on updating the
system is available at the following Web site:
When the system detects that the
hardware is not running at the expected level, the system applies
the correct firmware.
If you want to update without host I/O, shut
down all hosts before you start the update.
Complete the following steps
to update the system automatically:
- In the management GUI, select .
- Click Update.
- Select the test utility and the code package that you downloaded
from the support site. The test utility verifies that the system is
ready to be updated.
- Click Update. Select Automatic update.
- Select whether you want to create
intermittent pauses in the update to verify the process. Select one
of the following options:
- Fully automatic update without pauses
- Pause update after half of the nodes are updated
- Pause update before each node updates
- Click Finish. As the canisters on the system are updated, the management GUI displays the progress for each canister.
Monitor the update information in the management GUI to determine when the process is complete.
If you selected a fully automated update without pauses and the process
stalls during the update, click Resume to continue
with the update or click Cancel to abandon
the update and restore the previous level of code. You can also use
the CLI command applysoftware -resume to resume
the update.
If the selected to pause the update, click Continue to resume with the update. You can also use the CLI command applysoftware -continue to resume the update.
Note: When you update your system software to 8.1.0 from
a previous version on a system where you have already installed more
than 64 GB of RAM, all nodes return from the update with an error
code of 841. Version 8.1.0 allocates memory in a different way than
previous versions, so the RAM must be "accepted" again. To resolve
the error, complete the following steps:
- On a single node, run the svctask chnodehw command.
Do not run the command on more than one node at a time.
- Wait for the node to restart and return without the error.
- Wait an additional 30 minutes for multipath drives to recover
on the host.
- Repeat this process for each node individually until you clear
the error on all nodes.
