Creating An Echo Copy Pool - HP 12000 User Manual

Creating an Echo Copy Pool

Echo copy pools are created from physical library slots after a destination tape library is added
to the VLS automigration configuration. Each echo copy pool defines:
The single destination library
The single source virtual library
The slot range
The echo copy pool policy
Each virtual library has a SAN policy, and those used as a replication library will also have a
LAN/WAN policy. These policies are set up during the creation procedure.
To create an echo copy pool:
1. On the Automigration/Replication tab, expand Destination Libraries on the navigation tree
so that you can see all the related items.
2. Expand the destination library for which you want to create a pool.
3. Select Copy Pools on the navigation tree.
4. From the task bar, select Create Echo Copy Pool.
The CREATE ECHO COPY POOL screen displays.
5. Enter a start slot number and an end slot number for the copy pool from within the available
slot range shown.
6. Select the local library where your echoed virtual cartridges will be placed from the Local
Library list.
7. Select the storage pool where your echoed virtual cartridges will be stored from the Storage
Pool list.
8. For LAN/WAN echo copy pools, select whether your replication is for deduplicated or
non-deduplicated backups.
9. For LAN/WAN echo copy pools, select "Initialize via Tape Transport" only if you intend to
use this echo copy pool for the one-time process of tape initialization. (See
Initialization" (page
10. Select Next Step to set the policies.
1 1. Type the desired policy settings in the corresponding fields. The policy settings differ for SAN
libraries and LAN/WAN libraries, and are as follows:
SAN libraries:
Retention days – the number of days information is kept in the firesafe before it is deleted.
The default is two days.
Sizing factor – the percentage of space, compared to the actual size of a disk, allocated
on the virtual tape for the copy job. For example, if the sizing factor is set to 90% and
the physical tape is 100 GB, the allocated space for the virtual tape will be 90 GB.
