Part 1 of 2
Matt,
This applies to 5.1 and below.
Also, triple check all advice because I
could be wrong. I don’t have access to production NBU systems so this is
from memory and my notes. Also I am writing without providing a full explanation.
So I will include some notes at the bottom for you to review.
And learn some basic awk. A few days of
learning awk will save you weeks of typing. I train other NBU admins and that
is one of the first things they learn.
--My comments--
Freezing and suspending are media
attributes stored in the media database on the media server.
See field 15 of bpmedialist –l.
This is important because it means it does
not impact the image db on the master.
The images will expire regardless of the
media’s attribute unless you change the image expiration (bpexpdate)
A frozen media is never put back into
service unless you manually unfreeze it.
I think suspended moves back when the
images expire, but I’m not 100% certain.
Another thing to remember is you can only
freeze assigned media because only assigned media is stored in a media
database.
So to phase out LTO2:
-Make a copy of volDB on the master and
the mediaDB on the media servers so that you can roll back.
-identify which LTO2 media is assigned (storing
images) and which media is not assigned.
# vmquery -pn SCRATCH -l | awk '{print $1}'
This should list the unassigned media
-remove the Scratch LTO2 media from the
library and sync the volDB.
-If you have expired tapes outside the
library, use vmdelete to remove them from volDB.
-freeze the remaining LTO2 media using
“bpmedia –m MEDIAID –h MEDIA_SERVER_NAME”
