Hajee - I don't know why it would be so, but it seems that the snapmanager exchange license is a prerequisite. Have you tried installing the snapmanager exchange license ? You can look up all of your own licenses using the Products > My Licenses tool on support.netapp.com. Your post doesn't mention the version of DOT you're working with ? OnTap 8.2 has simplified license model with one SnapManager license. I hope this response has been helpful to you. At your service, Eugene E.

Claude - I don't see a reference to whether this it's CIFS or NFS you're implementing, but I do see it's DOT 7.3.3. (You may want to do an upgrade to a more recent version of DOT.) There's also Flexcache you may want to look at. With 7-mode it only works for NFS, but in Cluster it works with CIFS, too... I hope this response has been helpful to you. At your service, Eugene E.

Shailesh - Auto home dir mapping is seperate from your other defined cifs shares, which you can see with the 'cifs shares' command. All path names start with /vol, the root of the file system. No, this will not turn off all you other cifs shares. Issue the 'cifs homedir load' command after you've done the comment on the file to load the changes.

Sachin - Instead of the Cluster mode instructions I gave above. I would usually use the 'halt -f' the procedure you listed with 'cf disable/enable'. Either way will work.

Sachin - This would be on a 7-mode system. 'halt -f' will force the shutdown, so you wouldn't need to do the 'cf disable'. See the man page for the halt command.

Shailesh - It's the entry for /vol in the file that's causing your troubles, I think. All the rest of it is the standard default file, though every line should be commented out with a # char.

Shailesh - The error sez 'Bad entry /vol/vol0/vol while processing home directory paths. Homedir path doesn't exist, discarding this entry.' rdfile /etc/cifs_homedir.cfg Look for an entry of /vol/vol0/vol, and remove it. Best practice - I wouldn't keep any home dirs on vol0, though there is a default cifs share there. I usually tell students to remove it right after cifs setup.

For Shutdown: Sachin - Shut down any client applications, unmount LUNs, etc ... Log on to a mgt LIF on the second node. Do system node halt -node node1 -reason 'disaster coming' -inhibit-takeover true Then system node halt -node node2 -reason 'disaster coming' Turn off controllers, disk shelves and switches. Startup: Turn on switches, then shelves, then controllers. If autoboot isn't set then 'boot_ontap' from the sp or console. See also 'System Administration Guide' portion of the documentation.

Shailesh - Auto home dir mapping automagicly maps a user to a share for their home directory. See the /etc/cifs_homedir.cfg file for a vol0 entry. There's also the 'cfis homedir' command.

TingWei - DeDupe is working on WAFL 4K blocks. There's probably not many duplicate blocks in your DB dumps, and less likely that there'd be dupe zipped blocks.

Kalyan - I've recently done an upgrade from 5.1 to 5.2 on Linux and Windows installs of OnCommand Unified Mgr (DFM). It's very easy. Both the Linux install shell script and the Windows installer will prompt you whether you want to do a fresh install, or an upgrade. We had no issues with the DB upgrade, but you should still do a DB backup prior to the upgrade as best practice. I hope this response has been helpful to you. At your service, Eugene E.

Tomas - This is one of the most interesting questions I've seen recently ! The short answer - As far as I can tell compression and decompression is part of the kahuna domain - it isn't CIFs specific. You might want to try and look for a correlation between CPU(or kahuna) and cifs read activity in OnComand Unified Manager (DFM). I don't advise customers to turn on compression in high read activity environs, we do caution that it can be a CPU hit on decompression. I'm going to try and run some tests on my lab environ here, and see if I can tell you any more... I hope this response has been helpful to you. At your service, Eugene E.
