AID 5 provides redundancy by striping data across three or more disks and keeping the parity information on one of the disks in cach stripe In case of disk failure the surviving disks and the parity disk are used to reconstruct the lost data providing that data transparently to the user application Upon replacing the failed disk with a good disk the reconstructed data is written out to the new disk and when the reconstruction or sometimes referred as resyne process is complete the volume retums to a redundant state The capacity of a RAID 5 volume is the smallest disk in the RAID set multiplied by one less than the number of disks in the RAID set For example a four disk RAID 5 set will provide the capacity of three disks assuming all four disks are identical in size XA input Field Format gt Domain Workgroup Name A valid domain or workgroup name must conform to the following restrictions Name must only consist of characters az A Z 0 9 and the symbols _ underscore dash and period Name must start with a letter Name length must be 15 characters or less Host A valid IP address or a host name Host Name A valid host name must conform to the following restrictions Name must only consist of characters a z A Z 0 9 and the symbols dash and period Name must start with a letter A short host name length must be 24 characters or less A fully qualified domain n
