StorSimple is Microsoft’s on premises iSCSI SAN that extends seamlessly to the cloud providing 500 TB of disk space to on-premises file servers, users, and applications with a 4 RU footprint.
From time to time, Microsoft makes software and firmware updates available to the device. System administrators choose when to deploy these updates at a convenient time.
The device software updates are non-intrusive and require no down time. Under the hood, CAU (Cluster Aware Updating) is used to patch the passive node (controller), reboot it, seamlessly failover the device (clustered roles) to the other node (controller), patch the other node, and we’re all set.
The device also gets some disk and SAS controller firmware updates that require a ‘Maintenance Mode’ update. When there’s available Maintenance Mode update, you’ll see a message in the Azure classic portal under the device Maintenance page similar to:
This is a process that require down time. Here’s how we recommend you go about it:
wait for the device to reboot (both controllers)
Note that the Azure portal will show the controllers in Maintenance Mode during this time:
After controllers’ reboot, log back in:
The Azure portal will show information similar to the following image under the device’s Maintenance page.
