Maintenance Window -- Replacement of secondary Hard Disk on Leo ( 202.75.42.86 )

Date: 06 JAN 2006
Time : 12:00AM GMT+8

Description of Work
------------------------
We will be replacing the secondary hard disk on the server as the hard disk has been reported to be problems which causes unstability for the server lately this 2 days.

Impact of Work
-------------------
The server will be shut down in order for the hard disk to be replaced. We expect a max of downtime of 15-30 minutes for the hard disk replacement. The server will also encounter some performance degration after the hard drive replacement as we will need to rebuild the RAID 1 mirroring on the server which will take up some times. Further updates will be posted on this announcement.
