Re: raid
if the RAID comes from the XP10k, then it is preformated in these possible variants:
3D+1P
6D+2P
7D+1P
or with concatenation of the array groups
up to the
4x(7D+1P)=28D+4P
Are you speaking on the FS corruption on the host level (LVM) or on the disk failure on the XP10k pls?

Re: raid
rais 0+1
raid 5
If the disk which failed is on storage then storage take care of moving the data to spare disk(each disk group has spare disk in XP). When ur HP Engineer replace failed disk the array will copy the data back. U need not worry. Only u have to log a call with HP so that they can come and replace the disk.

Re: raid
As already stated, the XP will take care of disk failures. Depending on how the disk was failed the data will have been either reconsturcded or copied onto a spare disk. When the HP engineer replaces the disk the data will be copied back from the spare to the new disk. If dial home is configured on the array a call will be automataclly logged with HP and an enginner will be in touch to arrange for the disk replacement.
Hope this helps.
