RE: Foreign Configuration

Exhausted every option (even recovered 800GB of exchange data). Cleared the foreign config, while i was in CTRL-R, i noticed disk 2 in the ready state and i can not force it online. Reboot the server. Continue my exchange recovery process. Should disk 2 rebuild or do i need to does something to it so that it starts to rebuild?

RE: Foreign Configuration

No, you can't force online a Ready disk. With the array offline, and valid disks not showing foreign (or Failed), this is where you would do a retag. Why did you CLEAR the foreign configuration?!

RE: Foreign Configuration

You're already way past the point of no return for needing proffessional data recovery. Attempting a rebuild with 2 drives in unknown condition and unknown array consistency at this point will make it much, much more complicated for even a professional data recovery lab to recover your data and maybe even lead to unrecoverable data loss.

Even worse is if you cause some unrecoverable data loss that makes the exchange database unmountable after RAID data recovery, you will be spending thousands more to repair the database.

Here is the list of Dell Partners for data recovery:

i strongly suggest you at the very least you talk to each of them and get an impression of the costs you might expect and a free diagnostic done before making a decision to continue troubleshooting.

Good Luck.

RE: Foreign Configuration

I did a retag a couple days ago, remember? I cleared the config because i had to get past this issue so i could reseed the exchange DB. Everything is working now except drive 2 still in ready state. I guess i will replace that drive. When i do, should i be able to insert another drive and it start to rebuild or do i have to "do" something to initiate the rebuild?

RE: Foreign Configuration

As Theflash1932 stated, you have very few options left and no safe options(options that don't have a high chance of corruption).

Here's a list of dell preffered partners for data recoveyr:

Best of luck.

RE: Foreign Configuration

I have already moved past the data recovery (i recovered the data) but i still need to know how to replace/or get drive 2 to rebuild. Still is in the ready state and does not appear to be participating in the RAID. How do i get drive 2 to online state?

If I were to ignore the entire post and just answer your question:

You must assign it as a hot-spare.

RE: Foreign Configuration

It is weird to have to reboot a server in order to mark a drive hot-spare when the server is hot-swappable. Maybe it is me or maybe i am missing something? Ideally, i want to insert a drive and have it rebuild without any rebooting or making drives......

I marked it hot-spare and reboot the server. Drive 2 still does not rebuild or participate in the array. Is there something else i need to do?

RE: Foreign Configuration

You don't have to reboot the server. The only reason you would have to reboot the server to assign a hot-spare is if you were running a system that doesn't support OpenManage Server Administrator or remote access through a DRAC.

I marked it hot-spare and reboot the server. Drive 2 still does not rebuild or participate in the array. Is there something else i need to do?

Again, ignoring everything else in this thread, if your hot-spare is not rebuilding, then 1) your array is not actually degraded, 2) your array is offline, 3) the disk is not compatible with the array (mixing SAS/SATA/SSD, wrong size, wrong type, etc.), 4) the disk is bad, or 5) the array is broken and it cannot rebuild a missing disk. You could export the controller log to find out more information on it.
