Replace a failed Drive 1 in a PowerVault 725N

What are the proper procedures to replace a failed drive 1 in a PowerVault 725N. Currently the DRIVE 1 is reading "Online,Online(Errors)". I have not tried to reactivate the disk yet. Should I do this ?

This disk is part of a C: RAID 1 and an E: RAID 5. I have read many different posts on the proper solution for this and really need some insight.

First solution: shutdown the machine and replace the failed disk, then power up and run the repair option in the volume menu (which volume do I repair ?

Second solution: Shutdown the machine and replace the failed drive, then power up and break the failed mirror set and add a mirror set using the new replacement drive. Then reactivate the RAID 5 volume set then repair the RAID 5 set.

Obviously 2 very different solutions. I know I'm not the 1st person to have this problem so any information that can be shared would be very much appreciated.

Thanks
Nick

    Either one of those is fine.  The first option sounds like what you do through NAS Manager vs. the 2nd one shows how you do it through Array Manager.
     
    I prefer the second option.
     
    It did leave out the details of needing to write a signature to the disk and then upgrading it to dynamic before starting the repair procedure.  But go with option 2.

    Thanks for the quick reply. Is there documentation anywhere that has all the necessary steps. I'd prefer not to miss anything important. :)

    Thanks tomm0666. Through a fellow IT friend, I was able to find these docs. I used the NAS manager method which does the exact same thing as the Array Manager method only the NAS manager does everything for you automatically. It also started the mirror rebuild and the RAID 5 rebuild simultaneously. So the only thing you need to do is sit back and monitor.

    The mirror rebuild (80GB drives)took about an hour. The RAID 5 rebuild took about 3 hours.
