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. (configuring timezone offset take2, kicking up syslog debug level)

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: 06/08/2013 10:00 PM

Applying outstanding OS patches and VMware hosts in Dev Cluster

Posted on by

On May 25th I will be applying vmware updates to ESXi host in DEV cluster. This is a rolling maintenance and will not create any outages for running guest vm’s.  As they will be live migrated off one blade at time as its put into maintenance mode and patches applied.

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.

Multiple Netscaler changes

Posted on by

** Maintenance Announcement – NO service interruption anticipated **

The first change will be to deny non-secure SSL renegotiation, to address the vulnerability described in RFC 5746.  This will not have an impact on legitimate users, nor will they notice any changes.

The second change will be to replace the self-signed certificate used for logging into the management interface and changing the address (url) used for management.  This change will only impact those that log into the netscaler to manage it.   An email will be sent to those that will be affected.

The last change will to implement a fix for an asymmetric routing issue we’ve been dealing with.  This will not have a noticeable impact on existing services or users.  We have to make this change to allow “cross talk” among services.

VLAN Addition to Netscaler Trunk Ports.

Posted on by

** Maintenance Announcement – NO service interruption anticipated **

 

In conjunction with NOC we will be adding vlan 479 onto the port channel of the Netscalers.  This change will not result in any interruption of service nor will it be noticeable to end users.

The standby device will have the vlan added first, then made to be primary.  It will then have the vlan defined on it.  Once the addition had been verified to not have any negative effects the vlan will be added to the now standby Netscaler trunk port.  It will then be made primary again and verified.

HP 2910al-24g switch Firmware update

Posted on by

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

We are upgrading our 2910al-24g switches to the latest firmware. During the upgrade of the switch that provides the storage for the DEV VMware cluster will be unavailable, as such the Dev VMware cluster will also be shut down.

Production SANs are redundantly connected 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.
