Breaks in few servers at 2010-10-08 20:50-21:17

Schedule:

2010-10-08 20:50 - 21:17

Duration:

0:22 h

Affected services:

VCS, wiki, WWW, file services.

Reason:

The following servers will be rebooted due to SAN configuration changes.
- finglas.it.hiit.fi
- frodo.it.hiit.fi
- bilbo.it.hiit.fi
- universe.hiit.fi
- terae.hiit.fi

We changed SAN zoning from hard (port based) to soft (WWN based). Fabric 2 change went fine, no problems from hosts. When fabric 1 was changed one path to one of our disk arrays never recovered and one host started to lose connection to that disk array. To avoid further problems affected servers were rebooted.

Breaks to individual service wasn't longer than five minutes.
