Updates
There are regular maintenance releases and periodic updates to the array OS. Maintenance releases typically correct bugs and enhance features. Updates involve a major new release of the array OS with new features and capabilities.
If an array OS update is available for your array, you can accomplish the update in less then an hour for each array in the group. (If you want to combine your arrays as members of a group, each of them must have the same array OS version installed.) The update procedure works on one controller at a time and results in a controller failover. To avoid any data service disruption, make sure that the initiators connected to the array have proper MPIO timeouts configured before performing the software update.
If the HPE Storage Toolkit for Windows is not installed on the Windows hosts, be sure to configure timeout values appropriately. See System and Timeout Limits.
The array OS has an automated procedure to download and install updates. Or, you can download the array OS software from InfoSightâ„¢ at https://infosight.nimblestorage.com. If you do not have a user account, you can create one on your first visit.
