Problem with VMware ESXi v5.5 update 3B and HP storage driver

I recently updated a standalone ESXi 5.5 server through command line patching.  After the ESXi server rebooted and came back online, it showed no datastore and no access to virtual machine disks. 

I found a post about ESXi 6 updates causing similar issue when the HP Storage Array drivers had been removed during the update process. Since I still had my update logs pulled up in console window, I was able to locate a line that said "VIBs Removed: Hewlett-Packard bootbank scsi-hpsa <version>".

I was able to find a link to download drivers and transferred them to the ESXi server's /tmp directory:

The command to install the patch was:

"esxcli software vib install -d /vmfs/volumes/datastore1/hpsa-<version>-offline_bundle-<number>.zip"

After a reboot, I had access to the datastore again and averted potential disaster!
