Maybe off topic, but the subject of storage migration (both for primary and
secondary storage devices) comes up once every few months on this list. I am
really surprised that there is still NO official documentation on how to do
this properly, or an SOP for users to follow. I went through the same recently
and I had to search old emails threads to come up with a process doing it.
It’s about the time to produce some SOP for this process!
Just my $0.02.

H David,
I am not licensed to give support on a vendors propriety product, so take
all of this with a gain of the appropriate crystal;
Ad 1: you are right but migrating to another host should work as well.
Ad 2: There is a table that tells you that a snapshot or image is on a
certain primary storage but you’ll need to track it there. Easiest is to see if
the id of the primary storage still occurs in snapshot_store_ref. This as
example: ‘SELECT * FROM snapshot_store_ref WHERE store_id = <your old store’s
id>”. You might want to make sure all looks all right in storage_pool,
storage_pool_host_ref and storage_pool_work as well. And please keep in mind I
am looking at ACS 4.5 not CP even though the difference in this area should be
at most trivial.

We're in the process of phasing out primary storage in one of our zones
and had some questions about dealing with:
1. system VMs (Console Proxy & Secondary Storage)
2. what looks like (to me), left over snapshot artifacts
We're running CloudPlatform 4.5.1 with XenServer hypervisors and the
storage to be retired are Dell Equallogic servers.
For the first item I think all I need to do is mark the primary storage
on the Dell EQL's into maintenance mode and then destroy them so that they'll
come up on the new primary storage (already provisioned & configured in
CloudPlatform).
It's the second item that's giving me pause, when looking at the SR
associated with the primary storage I'm seeing disks named like:
* ABCServer_ROOT-685_20160905000250
and in CloudPlatform have found an associated volume snapshot with the
same date data. This seemed odd because I've understood that volume snapshots
should be on secondary storage.
I deleted the snapshot in CloudPlatform thinking that perhaps the disk
above would disappear from view when looking at the SR in XenCenter, but it's
still there. The impression I'm getting is that perhaps this is left over from
some volume snapshot failure to clean up?
How can I best chase this down? I'd like to retire this storage but I'd
like to make sure that once it's gone there isn't something in the database
that's still referring items there.
Thanks,
David
