You can just power off a switch and the systems will compensate as long as all hosts have active paths through both switches. If you want to try and avoid the timeouts, re-send of IOs, you can go into the hosts and set the link of the switch that is staying up as the preferred for IO so it isn't using the path to the switch that is going down. If you have to make changes to both switches, you should wait a few hours / day between reboots to ensure the path to the recently rebooted switch is healthy for all hosts before dropping the other side.

Not sure if this information is elsewhere, but when i go to Products and Solutions -> Latest Posts -> View All, each reply to a given post is listed as a separate entry, instead of as one conversation. If I drill into an area under Products and Solutions, for example, FAS, ONTAP, OnCommand and Related Plug-Ins -> Data ONTAP Discussions, then the conversations are listed grouped together. Is there a way to have them grouped at the top level?

If DC2 is a domain controller for the same domain the filer is a part of, the filer will automatically switch to it once it notes the primary is down.

What was the configuration on the filer side?

You need to define a default quota for that volume - then you should be able to do a resize without having to do a off / on.

The snapmirror relationship is maintained by a common snapshot between the source and destination. As long as there is one common, the relationship wouldn't have to do a full baseline. The snapmirror snapshot should show as "locked" as well. For snapvault, there will be additional snapshots on the source and destination but there will still need to be at least one common one. In most cases, a snapshot that is being used to maintain a relationship will be locked by the system. But it is a good practice to ensure that the purpose of a snapshot is well known before being condfident about removing it.

The options listed above would work. You could also ask your NetApp sales contact about getting a demo / trial license of SnapMirror for the migration process. They are generally open to a short term license to allow for the ease of upgrading.

Just checking, is the qtree security mode for the volume NTFS? What would be the permissions listed for the hidden share on the filer?

What is the configuration on the filer look like in terms of assigning LUNs to those servers via iSCSI?

rwelshman · ‎2014-02-17

The snapmirror.conf file manages the automatic updating of the snapmirror relationship. You don't have to put an entry in there if you are going to manually update the relationship.

Looking at the instructions it would seem that the data in those particular directories is data that has been exported from the DB probably due to regular DB maintenance. So if needed, it would have to be copied over manually.

You should be able to use the "snapvault restore" command to use the most current snapshot on the filer to copy the data back to the original. It might do a complete restore instead of a baseline though unless the OSSV database is still intact on the server and can match with what it sees on the filer.

what fibre switch are using? how are the zones configured?

rwelshman · ‎2014-02-05

What OS is the remote server? Does it use the OSSV client? Will the remote server still contain data once it comes back online or would all the data need to be restored from the SAN?

rwelshman · ‎2014-02-03

It is a part of the OnCommand - if you have that running, you can go to File -> Download Management Console. It is a straightforward install from there.

You would need to create a CIFS share of the SnapVault qtree which would provide read-only access to the snapvault data but it wouldn't appear under the previous versions of the primary volume.

rwelshman · ‎2014-01-30

The cifs shares are found in /etc/cifsconfig_share.cfg, you can copy the file over to the destination filer, or edit the file on the destination filer to include the share information that you want replicated. If you edit the file, you would need to restart CIFS on the filer to read it in.

What happens when you perform a rescan on the HBA - does it complete successfully? When you look in the storage adapters section on the ESX hosts, the number of visible LUNs doesn't change?

rwelshman · ‎2014-01-28

I think you can just use the "snapvault snap sched" command with either 0 for the count or a - for the time of the day, or even with -o tries=0 to prevent it from actually running the schedule, but manual updates should work as the schedule will be configured.

rwelshman · ‎2014-01-28

Which version of ESX are you running? How many hosts are connected? Do you have a LUN with ID 0 in the list?

You can't remove disks from a RG or Aggr - you would need to destroy it / re-create it (this would destroy all data in the aggregate unless you move it first). If adding disks to an aggregate will start a new raid group of type DP, you would need to add 3 disks. And if you could do that, you would only effectively get the capacity of 1 disk added to the aggregate. If the RG size is really large, you should try to add many disks to it to get useful capacity.

If you just need to do some testing, perhaps it would be easier to use a simulator instead of going through the process of switching the filer to cluster-mode. Is the 2040 filer a test system?

rwelshman · ‎2013-12-05

Sure, rlm gives you a console view of the filer like you were connected directly via a serial cable. When you go through the setup process it will prompt again for the rlm details but the current information should be listed and you can just keep hitting enter as you go through it.

The size is to ensure there is space for a core dump if the filer panics, there should always be a lot of free space in vol0. The minimum size for vol0 depends on the model of the filer.

rwelshman · ‎2013-12-05

If that is your end goal, snapshots won't be the best solution. You would have to look at some other outside tool to manage the backups - perhaps via a server that maps the share to a local drive.
