==== Cybertron Updates ====

**SYSTEM:** [[hardware:storage:cybertron|Cybertron]] and Unicron Network Appliance Filers

**DATE:** TBD

**START TIME:** TBD

**DURATION:** 2 hour

**Reason**:  Firmware upgrade.  Upgrading OnTAP8 to the latest version.

**Affects**:  There is no downtime associated with this work, however a small number of users may experience degraded performance on home or extra directories.

==== Sensoria Slave MySQL Server Reinitialization ====

**SYSTEM:** Sensoria-mysql database server

**DATE:** 2/8/2018

**START TIME:** 1300

**DURATION:** 1 hour

**Reason**:  Generate a mysql dump of the sensoria-mysql database

**Affects**:  The database will be placed in read-only mode for this maintenance.   Any writes to the database server will hang until the mysql dump operation is complete and tables unlocked.



==== Named Server Update ====

**SYSTEM:** ns1.ics.uci.edu ns2.ics.uci.edu

**DATE:** 1/4/2018

**START TIME:** 2:30pm

**DURATION:** 10 minutes

**Reason**:  Con added ns6.service.uci.edu into production.  Since it didn't allow internal view, our lookup to uci.edu domain would go to the root domain and hit their external view dns servers and have an odd result.  Adding forwarding zone for uci.edu to lookup from ns1.service and ns2.service resolves this issue for lookups internally.

**Affects**:  Users should not notice any difference.  It should stabilize lookups to uci.edu.


==== Linux Security Updates ====

**SYSTEM:** All Intel Base Linux Hosts

**DATE:** TBD

**START TIME:** TBD

**DURATION:** 2 hour

**Reason**:  Operating system updates are required to patch significant security vulnerability on **ALL** intel based computers.   

**Affects**:  Users will see intermittent downtime on all hosts and related services throughout the maintenance window.
