Storage Maintenance 4/4/2015 21:00

Posted on by

We will be performing two unrelated maintenance items during this window.

A) We will be reconfiguring physical links on our lefthand iscsi network (dropping a 8x 1gig lag merging switches in favor of a single 10gig link).

B) Reboot of capacity controller 1 to resolve ssh server bug. All traffic will be handled by controller 2 during the reboot.

Both of these maintenance events should have no impact to customers.

Start: 4/4/2015 21:00

End: 4/4/2015 23:00

If you need help you can contact us during the maintenance at: 7-7SIG (7-7744).

vCenter migration 10:00 – 22:00 Saturday February 7th

Posted on by

We will be migrating our existing VM hosts to a new vCenter server from 10am-10pm Saturday February 7th.  This will not impact running VMs nor your ability to RDP or SSH into the VM.

During the maintenance both the current and new vCenters will be active in the event you need to manage a VM (console, power on/off, etc).  However, you will need to check both as the VM may have moved.  The URLs for the vCenters during the maintenance are listed below.  At the conclusion of the maintenance the active URL of the new vCenter will be the same as the current vCenter.

Current vcenter: https://vcenter.sig.oregonstate.edu
Temporary new vcenter: https://vcenter2.sig.oregonstate.edu

 

Start: 2/7/2015 10:00

End: 2/7/2015 22:00

If you need help finding a VM you can contact us during the maintenance at: 7-7SIG (7-7744).

** 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.
