1.5 Managing a Device on AdvancedCopy Manager

AdvancedCopy Manager manages devices (physical disk) in ETERNUS disk storage systems. Each device is managed using its own unique identifier (AdvancedCopy Manager device name ). An AdvancedCopy Manager device name must be in the following format:

Table 1.6 AdvancedCopy Manager device name
Device name	Description
g?d?p? or Disk class name/mirror volume name: g?d?p? or g?d?	The characters "g," "d," and "p" indicate the following. ETERNUS disk storage systems The character "g" indicates a device number, "d" indicates an OLU number, and "p" indicates a partition number. Non ETERNUS disk storage systems (*1) The character "g" indicates a fixed value of 0, "d" indicates a serial number used on the server, and "p" indicates a partition number. For the SDX object Disk class name: Disk class name of SDX object Mirror volume name: Mirror volume name of SDX object For Logical Units (disk units) A device name of "g?d?" with no "p?" attached indicates a Logical Unit (disk unit).

(*1) About the device name of non ETERNUS disk storage systems <g?d?p?>
The character "g" is always 0 for non ETERNUS disk storage systems.
The character "d" indicates an AdvancedCopy Manager specific number that is unique on the server to which devices are connected. This number is different from that used by Disk Management.
The character "p" follows the same rules as the ETERNUS disk storage systems.

Devices not to be processed

For units of partitions, the following devices will not be processed by any part of AdvancedCopy Manager.

Dynamic volumes
Devices mounted at two or more locations

Use of the device name in the backup operation.
Each device name corresponds to a Volume (partition/logical drive) on Disk Management in Microsoft Management Console (MMC), but does not match a management number on Disk Management. AdvancedCopy Manager displays a block device name in the device list window to show the relationship between an AdvancedCopy Manager device name and a Disk Management name.

A block device name is in the following format:

disk?p?

disk?: A physical disk number, i.e., a disk number displayed on Disk Management

p?: The same value as <p?> in an AdvancedCopy Manager device name

The relationship between the AdvancedCopy Manager device name and the block device name can be referred to using either the GUI client or the device information display command.

For more information on the GUI client, see "Displaying device information" in the "ETERNUS SF AdvancedCopy Manager GUI User's Guide". Please refer to "stgxfwcmdispdev (Device information display command)" for details on the device information display command.

Note

For information on using disks with a physical size in excess of 2 terabytes, refer to "Using large capacity disks" under "12.1.1 General notes".
If Logical Unit (disk unit) operations are used, refer to "12.1.1.18 Notes on executing Logical Unit (disk) unit copy".

Target file system

The following device file systems can be registered in jobs:

FAT(File Allocation System)
FAT32
NTFS(NT File System)
