EVA Storage Array is down

8/24 Update: Mailman was successfully migrated and dcs-db1 is running again.

8/23 Update:  Attempts to use a "loaner" battery failed yesterday so we overnighted a replacement set of batteries which arrived this afternoon and worked.  The controllers appear to be working normally and all services except for mailman and dcs-db1 have been restored.  We are attempting to migrate mailman to another storage device and are determining which dcs-db1 databases can be restored.

Update:  The EVA5000 controllers use batteries to protect the cache.  All four batteries have failed, probably because they're ten years old, at the same time and the controllers will not work without a functioning battery.  We are trying to locate a replacement battery in the area.  Until we have a replacement, the EVA5000 will continue to be unavailable.

Original announcement: The HP EVA5000 storage system is experiencing problems with its fibre channel controllers.  We are attempting to repair them now and will have to power down the system.  Currently, services that use the EVA system are inaccessible becauseof the problem and will continue to be unavailable during the repair. 

The following is a list of known services that are affected:

• mailman archives
• dcs-db1 volumes
• dcs-config - affects NetReg
• dcs-webapps
• dcs-webmaint
• DCS-FILES - includes many older versions of class web pages and several research volumes.
