Yes, NetApp supports failover on loss of connectivity. Check documentation for “negotiated failover”. To avoid misunderstanding - it is not failover of interface. It is failover of complete controller - i.e. one controller is shut down and all services are migrated to partner.

aborzenkov · ‎2014-08-11

Each NetApp controller is independent and has own connectivity. So variant 1 will give high available connection for each controller. And yes, to ensure addresses are taken over by partner during controller failure you need to set partner interface.

I have FAS2240 which needs to be reverted to 8.1 after briefly running 8.2. Is SP/BIOS downgrade really necessary? I tried to downgrade SP to 2.1.3, but got rather funny results: SP sapdr> sp update http://172.17.0.200/FAS2200/306-02471_A0_SP_2.1.3_SP_FW.tar.gz -f Downloading package... Uncompressing package...

Every SAS shelf connected to FAS must have unique id.

And you say you have VSM. I told you QSM is possible in the very first reply.

aborzenkov · ‎2014-08-10

He did not say it. You cannot do VSM from 8.2 to 8.1.

Remove aggregate plexes in one location, move head from this location to another, remove FC-VI cards (you won’t need them for local HA pair), insert head in chassis, cable shelves for local configuration. Basically just it.

1. Snapshot is simply CP that was not removed. So when snapshot is created, additional CP is triggered. From now on it is not different from regular write path. 2,3. Snapshots are crash consistent. Some applications can do better and create application consistent snapshots. That's what various snap managers do. 4. Because it was implemented this way?

I think it checks whether address is currently active (configured on any interface), but may be it has additional undocumented checks.

aborzenkov · ‎2014-08-08

Are you sure? You still need to manually add ifconfig alias to /etc/rc - this does not happen automagically.

volume snapshot restore-file –vserver <vserver name> -volume <volume name> -snapshot <snapshot name> -path <path to file*> -restore-path <restore path**> Did not work because the volume was RO even if the restore path was a RW volume. snap restore to different volume is not possible by definition, RO or not RO.

1. You can perform VSM from 7G to 7-Mode. But ... 2. FAS25xx is supported starting wit 8.2.2. There cannot be any 8.1 on 25xx.

I am not aware of any way to manually designate primary path. For SAS shelves primary path was always selected on whole shelf basis, but different shelves in a stack normally are balanced between two adapters. I think I have seen different output, but it could have been in maintenance mode. I just briefly checked and all systems I have access to have whole shelf assigned to one primary path. System with 6 shelves in stack has them balanced between two adapters (3+3). That’s different from FC shelves where primary path was selected per disk.

aborzenkov · ‎2014-08-06

Not quite. It is always possible to resync as long as some common snapshot exists. SnapMirror snapshots are not special in this respect.

aborzenkov · ‎2014-08-06

I wonder, whether it is possible to create host route for your E-Mail gateway. Normally host route should take precedent over implicit local network route.

aborzenkov · ‎2014-08-06

Snapmirror snapshots have name pattern dest_name(sysid)_name.number. Of course, it may also be created manually, but I have never seen it. I do not understand second question. What “rebase” means here?

aborzenkov · ‎2014-08-05

You need to remove only SnapMirror snapshots. I am not aware of any issues caused by it- you can delete any snapshot at any time.

aborzenkov · ‎2014-08-05

You need to remove remaining SnapMirror snapshots on destination.

aborzenkov · ‎2014-08-05

In general, no (e.g. it is impossible to mirror non-qtree data into non-qtree).

aborzenkov · ‎2014-08-04

1. No for VSM, yes for QSM 2. No for DS14, yes for DS4243

aborzenkov · ‎2014-08-01

It will be deleted after second transfer completes.

OK, then please paste output of “df -h volume”, “df -hr volume” and “df -hS volulme for the volume where space is missing. Please, paste text in message, not link images.
