Few miscellaneous items: SQL, Exchange, Backups, Firmware and VMware

I will try to keep this one brief but informative. Last night I have done some recovery work as well as maintenance.

VMware:

Though still working on it, I'm working on recovering from the iSCSI issues we were having on Wednesday. As a result, I had to reboot all the VMHosts. Everything should still be up and running, and there was no downtime in services. I still have 1 ticket open with Compellent and 2 tickets open with VMware.

I have changed the iSCSI pathing from Passive/Active to Active/Active, this should provide a small boost in performance. Redundancy should still be in effect with the new multi-pathing model. (we were already multi-pathed on the SAN's iSCSI ports already.

Drobo:

• Applied a firmware update on the Drobo, and rebooted it.
• This affected 4 servers and backup sets:
• do-fs1, do-tech, postal, and do-sql: If you have anything to do with backups on any of those servers. Please verify your backups. I have ran the firmware update at 8:30pm. I believe this is before any backup window that we have, so theoretically nothing should've been affected.

POSTAL:

• Installed KACE agent.
• Stiill need to add Nod32, but need to research exceptions for Exchange before doing so. 
• Updates pending reboot. Did NOT reboot.

DO-SQL:

• Applied Windows Updates
• Uninstalled LANDesk Agent
• Installed the KACE agent
• Installed Nod32
• Added E:\Program Files\Microsoft SQL Server and E:\Data to the exceptions from RealTime scanning. If we see any specific performance issues due to realtime scanning, we'll revisit.

• Changes were made between 3:30pm and 11:00pm
