Question: Replacing failed drive RAID 1
I've had a PowerEdge 440 since 2007, and haven't done much with it, just the occasional reboot to install updates.
It has just kept running in a corner, however one of the drives have now failed.
I don't know much about it, but it is RAID 1, with Maxstor 70 GB drives.
I have bought two new SAS drives of 147GB each.
I intended to replace the dead drive and understand the virtual disk will remain at 70GB.
I'll run it for a week, and replace the 2nd drive which is OK at the moment.
Question is, will the virtual disk then automatically increase to 147GB?
If not do I need to do anything, like a rebuild?
Thanks

Thanks.
Can a virtual disk be re-sized within Dell SAS Manager to make use of this unallocated space once both drives have been replaced with 140Gb units?

You can, however, use that unallocated space to create a second array across the disks, but it will never resize itself (manually or automatically) to fill the entire space of the drives. If you want that space all accessible to existing partitions (in order to extend a partition, for example), then you would need to backup/image, put larger drives in, create new RAID 1 with larger drives, then restore your data to it.
