TS needed to be rebooted to bring it into compliance with the current AV regimine.

Novell server ST outage
ST student server was down when I got in today. Checked logs – couldn’t find any problems. Processor was at 24%. Couldn’t do anything useful at the console. Tried to check connections in the “monitor” screen – no response. Spawned other command lines – no response from “speed” or “down”. Powered off the server – it appeared to start up normally.
Webmail and wireless services slow
InfoSys is working to identify the source of heavy load on the server hosting Webmail and wireless authentication services. Until the problem is diagnosed and resolved Webmail service may be periodically disrupted and users may not be able to authenticate to the EMU wireless network. We are doing everything possible to resolve the situation rapidly and we apologize for the inconvenience.
Planned Outage of Multiple Services
Two core servers need to be taken offline in order to create images of their operating systems. Having these images is vital in restoring servers if they fail unexpectedly. The main services affected by this outage will be email, wireless access, and DHCP; however ALL network services could experience disruption.
Dad and Mail server down
Dad and Mail servers went down when the UPS signalling cable was removed.
This occured during the replacement of the control box for the matrix 5000 on the south rack. After the matrix was back on-line, the servers were powered back on.
UPS Failure During Diagnostics
During diagnostic procedures following UPS failure of 3/6, the affected UPS failed again. This caused a number of single-source power supply serversDuring diagnostic procedures following UPS failure of 3/6, the affected UPS failed again. This caused a number of single-source power supply servers to crash, most noteably the SIS running on the IBM iSeries (Jenzabar TEAMS 2000), the EMU web server (www.emu.edu) and the Oracle Calendar server.
To prevent this from reoccurring the following servers were moved to the north rack MATRIX UPS: IBM I-series, TS, and Tserve. ZW is still connected to the additional small 280 UPS. All test servers located on the north rack have been powered off – to increase run-time/decrease load on the MATRIX.
APC RMA number: 886725
contact: Ed
The control head has been determined to possibly be the cause due to other issues currently present. A new one is being shipped. We will need to test to see why, when removing the control head, power was lost. We will need to document when this occured – when placed in bypass, when removed, when replaced, etc.
A couple of issues were also discovered in the configuration of the powerchute agent on ZW. This is due to it being a fresh install – use the web client to modify the parameters.
UPS Failure , Several Servers Shutdown
The Matrix UPS providing power to the SOUTH RACK failed at about 8pm, Sun, 3/6. Discovered about 10:45pm. NetSYS tech support switched UPS to BYPASS mode about 11pm.
Servers known to be affected include: Calendar, Mail, DNS, CCTV, FS, FSAPPS. Exact status of servers unknown.
NetSYS techs discussed strategy and decided to take down all servers with single-source powersupplies and switch UPS back to OPERATING mode. This was done and UPS responded appropriately and all seemed to be working normally. Battery at 98%.
Special procedure done to the iSeries (AS400) box (a single-source power supply server). NetSYS worked with Loretta (via phone) to powerdown the unit. Pressed the right button on face plate and power-up proceeded to LOGIN screen on console within 5 minutes.
As a precaution DNS server moved to NORTH Matrix until we are sure all problems with SOUTH Matrix are resolved.
Some additional servers had to be restarted to insure they were running properly. In the course of doing these server restarts it was found that the MAIL server would not start properly. This may be due to changes made last week for the LDAP services. See separate Outage log setup for the MAIL server.
Lancaster network outage – all day
The Firewall and router for the Lancaster campus will be upgraded on March 1. This means the internet connection (and connection to/from EMU) will be sporatic throughout the day. Due to the nature of the changes – it is impossible to say exactly when the network will be unavailable or for how long.
Wireless outage in Common Grounds
Ciscoworks showed the WAP in common grounds to no be responding.
It ended up that someone moved the patch cord to the WAP – and connected it to the computer. Since there is a power injector for it, wow – no power – it didn’t work. Now the question is – did it hurt the computer. It wasn’t on since it was missing the power cord.
Phys plant and oakwood network outage
Also all of Oakwood is down.
Went to oakwood – power is good, swapped SX modules, both are fine.
Went to maplewood, swapped SX modules, both are good, however, they are now both working – go figure. If the link from maplewood goes out again – replace switch. If link to PP goes out, replace SX module.
Checked for loose fiber – didn’t find any.
