Solaris update 8 was likely the last one released before Oracle acquired Sun. So later updates are Oracle branded.

Is FlexClone an option?

aborzenkov · ‎2013-09-23

A matter of habit I guess. But I like to retain possibility to quickly perform giveback if something goes wrong during takeover. Otherwise in simple cases it probably does not matter and in complex cases editing /etc/rc alone may not be enough and you need temporary adjustments on partner as well.

What do you call "DR volume"? I have never seen such term in NetApp documentation.

8.1.3 is available for quite some time already.

1. Yes, you correct. 2. Again, you are correct. Nothing happens, partner controller is not up anyway. 3. In your case state of each filer is known at every step. In case of disaster it is unknown whether partner or interconnect is down. 4. Good question. I'd like to get answer too

Aggregate is dedicated to one filer. Concurrent access from both filers in HA pair to the same aggregate is impossible.

aborzenkov · ‎2013-09-17

Moving address to different physical port almost certainly requires adjustment to network infrastructure. I cannot predict how long it may take. Takeover should be non-disruptive for ESX access. If it is, your HA pair is no more HA in the first place and no NDU would be possible.

Takeover filer; edit /etc/rc for new configuration; giveback.

Yes, best practice is to assign all disks in a stack to the same pool. But it is possible to mix them as we'll. You may need to use force option or do it from maintenance mode.

aborzenkov · ‎2013-09-17

You need manually assign drives to the correct pool.

aborzenkov · ‎2013-09-16

Yes, it's possible. You need to connect host to both filer heads. There is no filer level failover when FC connection breaks - hosts at use supported multipathing software to handle it.

aborzenkov · ‎2013-09-14

No, it is not possible. You could simply move content out of qtree later.

aborzenkov · ‎2013-09-11

I am afraid, not. Partner will need to see exactly the same tape device under the same name, that is configured in backup software. The only way (at least, known to me) is to use 3way backup via remote NDMP tape server.

aborzenkov · ‎2013-09-11

You need to add exactly the same commands.

aborzenkov · ‎2013-09-11

Destroy all aggregates on shelf, zero spares, remove disk ownership, shutdown filer, disconnect shelf. Now you add shelf online to any other filer.

Does https://kb.netapp.com/support/index?page=content&id=1011421 help?

This is exactly X1139 or X1140.

There seems to be some misunderstanding. You cannot export NFS via FCoE, but CNA adapter provides both LAN and FC functions via the same physical connection, so you can use LAN part as normal (although possibly more expensive) LAN adapter.

LUN show -v displays size, occupied by LUN, at least on recent enough DataONTAP.

aborzenkov · ‎2013-09-04

You need to use port_name for zoning and masking. Fabric name is internal port wwn assigned by switch and is not used for device to device communication.

aborzenkov · ‎2013-09-03

Historically interface name size was limited to 15 (or was it 16?) characters on Unix. You most likely hit this limit.

aborzenkov · ‎2013-09-03

Those short cables are to get multipath drive connection, so you should be able to remove them to connect extra shelves.

aborzenkov · ‎2013-08-30

You will need to change cabling offline (controllers shutdown). But I do not see any reason to do it. The more HBA IO is distributed over, the better. The only reason would be if you plan different shelf type.
