** Maintenance Announcement – NO service interruption anticipated **

We are upgrading our StoreVirtual firmware from  LeftHand OS 10.5 -> LeftHand OS 11.0

Production and Dev SANs are redundant and maintenance will have no noticeable effect on these SANs, meaning that the OSU systems used by students, staff, and faculty will not experience a service interruption.

Start Time: 12/21/2013 at 9:00 PM

End Time:  12/21/2013 at 4:00 AM

** Maintenance Announcement – No service interruption anticipated **

We will be applying a firmware update to our iSCSI switches that support our StoreVirtual SAN. This is the storage network that back’s our VMware infrastructure.

We do not anticipate any service interruption. Our switching is redundant, we will only change the switches one at a time, and the changes should not be service interrupting.

Start: 11/09/2013 10:00 PM

Part 4 The Saga Continues.

Everything was nice and quite for a few months for us here regarding this issue. Then classes started and things got a little busy and the problem is back with a vengeance. We have been getting paged once per night. It will be a random switch in the stack not always the same one. We have logged a support case with HP and we got the standard teir1 response of update to the most current firmware. So we will be upgrading to W.15.12.0011 during our next maintenance window. If this does not address the issue we will continue to poke away at the problem!
