There is a performance monitor application that you can install via DFM / Operations Manager which will show you performance metrics. It works with 7-mode, but I haven't worked with Cluster-Mode so I'm only assuming it would work for that.

Have you tried using a \ (or /) in front of the comma to see if it would escape it? I think it is parsing the data after the comma as a potential additional parameter, so if you can't escape it, I don't think ndmp will handle it.

Unfortunately, I believe you have described the necessary procedure to completely wipe all disks. Fortunately, most of the work can be done in the first stage of sanitizing all but the three disks in the root aggregate. Creating a new aggregate and moving the root volume shouldn't take more than a few minutes, reboot and then the last three disks can be sanitized.

Looks like the link is broken on Jupiter1 0g. Can you do an "environment status"? Might be a failed cable or module.

The problem with CIFS / NFS is that Windows has a richer ACL per file than Unix. So if you try to access a Unix-security volume with a CIFS share, the security permissions will be limited. However, if you use mixed mode, or even create a NTFS security volume, you can still access it from Unix (if it is exported as well as a cifs share) and keep the richer security settings.

You can also trying to send a remote ssh command from another server to see if it replies: ssh root@<filername> df -Ag for example.

What version of Vmware? Can you check on the Vmware server to see what it set as the preferred path?

Are you running SIS on any of your volumes? Does this happen every day?

If you can see your licenses for the filer under the NOW site, the OnCommand license will likely still be called "dfm" something or other.

If you want to reduce the amount used in aggr0 - you can reduce the size of vol0. Or reduce the size of the aggregate snap reserve.

ifconfig mainvif `hostname`-mainvif mediatype auto netmask 255.255.255.192 partner mainvif ifconfig mainvif alias 169.41.6.147 netmask 255.255.255.192 What IP is in the /etc/hosts file for the hostname? Why are you specifying an alias? man ifconfig: " alias Establishes an additional network address for this network interface. This is sometimes useful when changing network numbers and one wishes to accept packets addressed to the old network interface. It is required when creating IP vir- tual host addresses. May not be applied to a network interface which is part of a vif."

I would suggest using a NFS mount for simplicity - you can grow it on the fly, you can move it to another VM or physical server, if needed, you can take snapshots for fast backups, etc. My question would be is there any limitations to re-sharing the NFS mount via CIFS and HTTP? I wouldn't think so, but I haven't done it myself.

One unsolicated comment: it is recommended to create a new volume for data access instead of using vol0. Vol0 should only contain the Data On Tap operating system files. For the export, what is the result of "exportfs -q /vol/vol0/soft"?

A takeover / giveback is sufficient for a card install. Once a head has been taken over by the other head, the head can be shutdown and work completed on it. Ensure that there are free PCI slots and that the type of filer can use the fibre card in the available slots as well.

Is the volume offline, under vol status? If the volume is at 100% full there can be issues with the system using it as no writes can happen. The filer will also not be happy about the 100% full volume either.

If you look in Device Manager at the Disk Drives - the manufacteur of the disk is usually listed - so Netapp disks would be a NetApp LUN, for example.

1) Yes, as long as the settings within Vmware for the datastores are set as recommended by NetApp and the VMs are runnnig tools which has set the SCSI timeout to at least 60 seconds, they should survive. (Just did this last night on a 6070 filer with over 370 VMs running). 2) If you want to split the connections between Switch A and Switch B (instead of just going to switch A or switch B), then you'll have to change the VIF from a multimode (i'm assuming it is multimode) to a single mode (unless the switches you are using can port channel across multiple switches?) If you do have to change the VIF type, it will require removing the old VIF and re-creating a new one - which will be service interruption, although you can cut and paste the commands in and have it complete fairly quickly if all goes well. What sort of constraints are you under in terms of outages?

I would recommend checking the disk timeout on the Xen Server - if it is too small, it would notice the delay during the failover / giveback process and cause an issue.

Can you check the firmware? "To mix ESH and ESH2 in the same loop, the ESH modules must be running FW94 or later, and the ESH2 modules must be running FW13 or later."

I believe the solution to this would be a fix in the Java Control Panel. When you open the page, you should see the Java icon pop up in the taskbar. Right click on it and select Control panel. Once you are in the Java Control Panel, select Advanced -> Security -> General and uncheck TLS 1.0.

Do you mean something like running a "snapmirror status" on the cli? The snapmirror log allows contains some progress data.

What command are you using to try the delete? What is the error message?

Do the disks show up on the VM (under device manager)? How did you add the addtional controllers to the VM? Are there extra physical controllers in the ESX host that were assigned to the VM?

exportfs -a will load the file without exporting something that isn't in the file. exportfs -w <path> - will let you export the current exportfs list to a file - if you wanted to do that before making the file change. This will work-around the problem you experienced, but to do a comparison - you'd have to do a check via an external system (for example: linux diff).

If you have the SnapDrive software installed - it can create the LUNs for you. So you would just need to have the volumes available on the filer. With a CIFS share created. Then, on the SnapDrive software, just step through the Create Disk options and it'll create and add the disk for you. There should have been a UserGuide link available where you downloaded the SnapDrive software.
