ICS Maintenance June 18, 2006

In order to accomodate a 12 hour facilities shutdown on June 18, 2006, ICS Computing Support will begin shutting down non-critical ICS infrastructure in the ICS Datacenter at 5pm on June 17, 2016.

Facilities High Voltage Team has been performing preventative maintenance on many of the campus building transformers, switchgear, and breakers. While performing maintenance we have been able to identify and repair many equipment deficiencies and reduce the possibility of electrical failures and outages.

Facilities High Voltage Team has scheduled preventative maintenance on Computer Science T-18 & T-19 transformers and switchgear for Saturday, June 18th, 2016, from 5:00am-5:00pm

In order to perform this maintenance it will require a 12-hour electrical shutdown to the entire building. The only power will be emergency power.

ICS will be taking this opportunity to perform maintenance on multiple systems that would individually cause significant disruption for users.

Effects on Critical infrastructure will be not be affected bavailable during this period. That infrastructure includes:

• ICS Home Page: http://www.ics.uci.edu
• ICS Email Systems
• ICS Home Directory (qualified with exceptions)
• ICS Samba Service (IGB Samba will be unavailable)
• ICS Samba Service
• Many ICS hosted websites (contact helpdesk to see if yours will be available).

Plan on brief outages on several ICS systems during the day. A more specific schedule will be provided later. These items are required to implement network redundancy inside the data center and perform maintenance on systems:

Summary

• ICS NetApp Storage Outaages: Several service interuptions are expected to setup network switch redundancy.
• ICS shared space: Move /net/tron/support0_tainer_sata/shared/ to net/cybertron/vol2/ics_shared
• SGE: Central Spool data relocation
• Subversion data relocation
• Gitlab data relocation
• Complete Data Center Reboot
• Move MySQL
• Move ugrad accounts
• CentOS and Ubuntu OS Patches and Updates
• New UPS installation
• Bunker CentOS7 Upgrade
