Problematic server... Intel Raid to another controller?
Posted on 2010-08-23
This is a production SQL server. Windows 2003 R2 x64. Supermicro motherboard, 24gb ram, Quad-Xeon.
It has on-board Intel raid, configured to Raid 1 (for OS), and Raid 5 (for data).
Configuration is as follows:
Drive 0--RAID 1
Drive 1--RAID 1
Drive 2--RAID 5
Drive 3--RAID 5
Drive 4--RAID 5
Drive 5--RAID 5
All drives the same model Seagate SATA.
The Intel Raid Manager has been problematic. I found the manager to be quite problematic on regular workstations as well. Randomly, Intel Manager pops up with "raid degraded" message. This, however, can be quickly fixed by right-clicking on the drive (in the Intel Manager software), and selecting "Normal". Poof--and the problem is fixed, Intel proceeds to rebuild the drive. The same happens when Intel Raid Manager claims that a hard drive has failed. One click and it's online. (buggy software?) Also, spontaneous reboots have been occurring with this machine as well. I checked the logs--too quick for even Event Log to catch the problem, so no trace.
But this is not the main issue. I am trying to move this machine to a different RAID controller, Adaptec to be specific. Data on the server is crucial. Usually, in raid cases, I was always able to make an Acronis Image (.tib), and move it to another pre-configured raid. With this machine, however, even Acronis fails ("cannot load linux kernel" message comes up. CD is not scratched and works on all other raid machines).
Are there any other ways that I could move that machine from Intel to Adaptec controller, without loss of data? The Intel Raid Manager is a mess, and it's not reliable enough to be used further. Any suggestions?
Thank you very much!
