Info
On HPE Primera and HPE Alletra 9000 systems, an unexpected restart of a controller node during planned shutdown/restart of another node may occur after updating the operating system.
To avoid this rare condition, install Upgrade Tool version 48 (UT048) or later
before
updating HPE Primera OS to 4.5.x or updating HPE Alletra 9000 OS to 9.5.x.
Scope
This issue affects HPE Primera 600 Storage arrays running OS 4.5.0 through 4.5.3 and HPE Alletra 9000 arrays running OS 9.5.0 through 9.5.3.
Resolution
To verify the installed version of the Upgrade Tool, run the command
showversion -b
after login to the array cli:
NOTE
: If the Upgrade Tool version installed is 48 (UT048) or later, then no further action is necessary.
If the Upgrade Tool version installed is earlier than 48, then install the latest version of the Upgrade Tool. When connected with HPE InfoSight, the latest version of the Upgrade Tool will be automatically downloaded and installed. Without HPE InfoSight, manually download the latest version of the Upgrade Tool from
My HPE Software Center
and load it using the storage system's user interface on the System/Software page.
After the installation of the latest version of the Upgrade Tool kit, checkhealth will report the following information on the file component if the HPE Primera array is running OS version 4.5.0 through 4.5.3 or HPE Alletra 9000 OS version 9.5.0 through 9.5.3. In that case, this information is expected, can be ignored, and will be removed in a future OS release:
