Hello Ray PD 2 has hit a critical threshold for bad blocks and is going to fail. It may fail in the next hour, or it may go on for years without failing completely. I don't know exactly what you have on the other array that contains a copy of exchange, but I'm guessing you are performing backups to that drive. Removing PD 2 will cause all data on that array to be lost. There is no way to keep the array intact since it is RAID 0. I would suggest performing a backup before you replace the drive. After you replace the drive you will need to delete and recreate the RAID 0. After the array is recreated you can reinstall exchange onto the partition. One thing I would suggest double checking is whether or not this is a hybrid array. Depending on the utility you are using to view the array, it may show a RAID 1+0 as two RAID 0 arrays; which is not incorrect since that is essentially what they are, but some utilities will fail to report that they are spanned together via a RAID 1. I would recommend reviewing the array information from the controller BIOS or one of our utilities to be sure of the RAID levels. If it is indeed a RAID 10 then you can just pull the drive out and replace it without a service disruption, but if they are just RAID 0's you will lose exchange. In that case you will need to recreate the RAID 0, reinstall exchange, and restore data from backup. Thanks
I have a question that involves RAID I have exchange server 2007 running on a Dell PE2850 with 6 Physical hard disks. The PE2850 has hardware RAID in the following configuration. Array Disk 0:0 & 0:1 c:\ drive RAID 1Array Disk 0:2 & 0:3 D:\ drive Raid 0Array Disk 0:4 & 0:5 E:\ drive Raid 0 Disk 0:2 is now failing for "Predictive Failure" and has failed the SMART Diags test. My C:\ drive has windows server 2003My D:\ drive has a live copy of exchangeMy E:\ drive has a copy or exchange so exchange must be replicating from D:\ to E:\ correct ? My question(s) is, can I just remove Array Disk 0:2 and replace with a new hard disk?what happens with exchange ? From what I understand, with RAID 0, one drive failure destroys the array ? I'm worried that If I removed Array Disk 0:2 that exchange will fail.Will exchange use the copy of its folder instead. Previously Array Disk 0:0 failed and I replaced it with another disk no problem, but this was RAID 1 ( Mirroring ) Any help appritiated, Ray..
Exchange 2007 RAID 0 ?
