Do Dell perc 6i cards support online expansion of a raid 1 array when both drives have been replaced with larger ones?
For example the the Logical Drive 0 (LDO) has two member 73gb drives.
We have two new 147GB drives available and inserted into the spare slots of the server. (not worried about final drive location in system)
Can I remove each 73gb and replace it with a 147gb and then grow the raid 1 array using the MegaCli tools (version 4.00.11)?
Will the controller support online expansion?
What command switches are required to complete the reconstruction/grow/expand if supported?
Alternatively I will have to create a new LD on the controller (2x 147gb raid1), pvmove the data, and dd /boot over and reinstall grub etc.
