HP 2910al-24g switch configuration

Posted on by

** Maintenance Announcement – No service interruption anticipated **

We will be applying a configuration change 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.

Change to Nexus 7Ks

Posted on by

On Thursday the 28th we will be working with NOC to try and resolve an issue that arose when the 15 subnet was placed behind the new firewall.  Starting at 10pm NOC will re-enable the other member of the VPC and then implement the fix.  We will then verify that things are working as expected.  The estimate is for about 10 minutes total.  During this 10 minute window mail will not be sent, but queued on the webheads.  Those that use proxy.oregonstate.edu will not be able to view the Homepage or any other CWS hosted sites.

Start: 3/28/2013 @ 2200

MCC Blade Center Fiber Migration to Nexus gear

Posted on by

** Maintenance Announcement – No service interruption anticipated **

We will be moving our Milne Blade Center from mccnet101 to nexus gear. We will migrate non-redundant VMs to KAD b210. During the migration we expect to drop 1~2 packets when we cut over from the active fiber pair on mccnet101 to the nexus gear. Though we will do not expect a service interruption as all critical VMs will be moved to our other data center first.

Start: 4/27/2013 10pm

vCenter Migration

Posted on by

** Maintenance Announcement – No service interruption anticipated **

We will be migrating from our old vCenter servers to our new vCenter servers. There will be no interruption of service. During the move if Administrators need to gain console access to their VMs they may need to check both vCenter servers to find their VMs. After the moves are complete Administrators will access consoles from the NEW vCenter server.

The new server to connect to is: vcenter.sig.oregonstate.edu.

Regular remote access mechanisms like ssh or remote desktop to the VMs will be unaffected. All VMs and their services will continue to run as normal. There should be no customer impact.

Start: 03/30/2013 9:00 PM

End: 03/30/2013 23:59 PM

LeftHand OS upgrade 10.0 to 10.5

Posted on by

** Maintenance Announcement – DEV VM service interruption anticipated **

We are upgrading our StoreVirtual firmware from  LeftHand OS 10.0 -> LeftHand OS 10.5. During the upgrade of the storage that provides the DEV VMware cluster will be unavailable, as such the Dev VMware cluster will also be shut down.

Production 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: 03/26/2013 at 10:30 PM

LeftHand SAN physical node moves

** Maintenance Announcement – No service interruption anticipated **

Applying outstanding OS patches and VMware tools to our vSphere Infastructure

Posted on by

** Maintenance Announcement – Partial service interruption anticipated **

We will be patching the OS’s and installing the latest VMware tools against our vCenter server infrastructure. During the first part of this maintenance window support personal will not be able to access vCenter. Because of this support personal will not have remote console access. For example, if a VM has a kernel panic then the support personal will have to wait until maintenance ends to resolve the issue.

Regular remote access mechanisms like ssh or remote desktop to the VMs will be unaffected. All VMs and their services will continue to run as normal. There should be no customer impact.
