HP 9000 Virtual Library System - Manual (Page 57)

LAN/WAN libraries:
•
Priority — the priority this echo copy pool takes over other copy pools during the backup
window. This can be High, Medium, or Low.
•
Deduplication Timeout (only if you selected deduplicated replication on the previous
screen) — if the cartridge fails to deduplicate within the timeout limit you set, the entire
cartridge is copied over in non-deduplicated mode.
•
Send notification if cartridge not replicated in — the copy pool threshold. The system will
send a notification if this many hours have passed and the cartridges have not replicated.
•
Start mirror of Out of Synch cartridges — see above for LAN libraries.
•
At End of the Policy Window – see above for LAN libraries.
12. Select Next.
13. Beneath the policy settings you just entered, enter the details of the window duration:
•
Start Day – the day of the week on which the echo copy job begins. HP recommends
that copies are scheduled on a different day and/or time window from other backup
activities.
•
Start Time – the time at which the echo copy job begins. HP recommends that copies are
scheduled within a different time window from other backup activities.
•
Window Duration – the number of hours available during which the echo copy job can
take place. If the migration does not take place during this window, the job is maintained
in the queue until the next start time.
For SAN destinations, HP recommends that you schedule mirror copies on a different day/time
window than backup activities. For LAN/WAN destinations, HP recommends that you allow
mirror copies to run 24 hours a day unless there is a need to restrict the use of LAN/WAN
bandwidth during certain periods of the day.
14. Select Add.
The window refreshes, and the availability window you just added is moved to the Current
Availability Windows section of the screen.
Repeat steps 12 through 14 for as many availability windows as you need.
15. If you need to delete an availability window you just created, select Delete corresponding to
that window.
16. Select Submit.
If the pool was successfully created, the Copy Pools screen displays, along with the message,
“The echo copy pool [echo copy pool name] was successfully created.”
If the pool was not created, the CREATE NEW ECHO COPY POOLS screen refreshes and provides
an error message at the bottom of the screen. Failure to create the pool most often occurs
because the slot numbers chosen are outside the available slot range. “The start slot is not in
a free range of slots” displays if only the start slot or both the start and end slots are out of
range. “The end slot is not in a free range of slots” displays if only the end slot is out of range.
17. If the new pool is not created due to a slot range error, repeat this procedure and select slots
within an available range.
Creating Virtual Tapes
Virtual tapes are created automatically when:
•
A pool is created that includes physical tapes.
•
A Load Media for Restore, Load Blank Media, or Load Media for Overwrite is performed.
•
A tape is moved into an echo copy pool by some means other than automigration.
