Disk Management - Spanned Drives Issue
I have three external SCSI RAID arrays of 5 drives each. They are 2 units by
Medea called VideoRaid. One unit has 5 drives that are hardware RAIDed and the other unit has 10 drives that the first set of 5 is one array and the second set is one array. They are daisy-chained and connected to a video editing workstation (PC/Windows XP) through an Adaptec 29160 card. The data on the drives totals 3.5 terabytes. The problem is with Windows XP Disk Management. The arrays show up as 3 disks in Windows. These drive sets were orginally spanned to make one large drive (the W drive). In the Disk Management console, two of the drive sets are Online but say Failed and the third drive set says Unallocated. It seems that the span has been broken and the configuration in Windows has been corrupted. The physical drives are fine. I have checked them in a pre-Windows boot environment called SCSISelect by Adaptec. All the cables are connected properly. How can I repair the situtation? |

Could I use Windows' System Restore to restore back to the point in time
before the spanned volume broke? "Matt" wrote: I have three external SCSI RAID arrays of 5 drives each. They are 2 units by Medea called VideoRaid.

Youre RAID controllers software would or should bring up the arrays as
installed,doesnt adaptec offer software......Also,go to run,type:cmd In cmd typeiskPart In DiskPart type:list disk Then type:list volume Type:HELP for all cmds,sometimes DiskPart will list diffrent than the OS..Also,with all the RAID configurations,why not run windows server...Server has 10X the software specifically for multiple RAID configurations than xp,chk MOM software for windows server from microsoft....

Disk Management - Spanned Drives Issue
You don't say if there is any need to recover data - that could be pivotal to
your choice of action. Basically, failure of the first disk in a spanned set loses access to the data on ALL the disks. In other words, spanning reduces fault-tolerance whereas (certain types of) RAID increase it. It might be possible for a specialist company to recover the data, but I wouldn't hold-out too much hope, and it will cost a packet. There is also the consideration that spanninng is a software arrangement, and as such is vulnerable to registry corruption. A pure hardware-based solution which presents the disks to the OS as a single 'drive' is bound to be more efficient and reliable. It looks as if you might have to rebuild your disk-array anyway, so if possible I'd look at putting all the disks into one RAID array. That would eliminate the need for spanning. |
