If you want to restore data that was backed up with LU to Partition, AdvancedCopy Manager CCM can restore the contents of a partition to a volume by specifying the extent start position in the copy source volume, the extent size, and the extent start position in the copy destination volume. In this manual, this function is called "Partition to LU ".
After restoring the backup data stored to tape in "3.4.2 Backup to Tape" by tape backup software to the partition of a temporary volume (called "new volume") different from a backup volume, Partition to LU is used for restoring the backup data from the partition of a new volume to a business volume.
The new volume must be able to reference from the tape backup software.
Figure 3.14 Copying Volume to Partition
Copy Pair Format
(1) Copy source ETERNUS name
(2) Copy source logical volume number (*1)
(3) Extent start position at the copy source volume (block units) (*1)
(4) Extent size at the copy source volume (number of blocks) (*1)
(5) Copy destination ETERNUS name
(6) Copy destination logical volume number (*1)
(7) Extent start position at the copy destination volume (block units) (*1)
*1: Specify the hexadecimal starting with "0x". (ex, "0x1" or "0x0001")
Point
The copy pair format of Partition to LU is the same as LU to Partition. However, the differences in the content that are specified are as follows.
Specification Items | Contents That Are Specified with LU to Partition | Contents That Are Specified with Partition to LU |
|---|---|---|
Extent start position at the copy source volume | Start position of a volume (0x0) | Start position of a partition |
Extent size at the copy source volume | Volume size | Partition size |
Extent start position at the copy destination volume | Start position of a partition | Start position of a volume (0x0) |
Adding Copy Pair
Refer to "Adding Copy Pair" in "3.4.1 LU to Partition" for the procedure to add a copy pair. However, check the size and create a partition by re-reading the copy source/destination in LU to Partition and the copy destination/source in Partition to LU.
