Entering navicli commands

Question

We like to zero our discs of a NS20. But when I put the NAVICLI command into the CLI COMMANDS line at the Web-interface it calls "/bin/sh: navicli: command not found". Do I have to switch to a specific library first or .... Even when I try to enter the command in the SSH shell it responds the same.

Best regards,

if you want to zero ALL disks and re-install DART please contact customer service for a procedure to do so

Hi Hans,the reason is that navicli is not in the path so you have to specificy the full path like /nas/sbin/navicliPlease be carefull when playing with navicli and make double sure that the LUNs arent used or referenced by the Celerra any longer.When i doubt I would suggest to contact EMC customer service.Starting with DART 5.6.45 we have added CLI commands and Celerra Manager GUI support to de-provision storage safelyregardsRainer

in the ssh shell it is: $ /nas/sbin/navicli Regards Peter

the first five disks in the first DAE is where the Clariion OS, vault area and the Celerra OS is
I dont think you can just zero these

Even if you Flare and vault wont mind you would have to get DART re-installed by EMC customer service afterward

you need to unbind LUNs first, you have to be very careful not to unbind luns used by DART.

first run:

navicli -h storagegroup -list

you should see HLU column for storage group Celerra_ns20int1 or something of that nature, now you need to figure out which ones are not in use by Celerra Dart. On my NS20 these DART luns are ALU 0-5. You will see that they are very small size, some are 11g and some are 2G.

So once you have LUNs identified, you need to remove them from the storage group, unbind them and delete zero them out. Download Navisphere Command Line interface manual.

Hi Hans,I am not sure what is the purpose of doing it. Are you trying to re-install the Celerra or simply deleting data on the backend - or planning to send the disks or unit to somewhere else.Is this Celerra still going to be a live box? If yes, I'll prefer to get in touch with local EMC team or call EMC Support desk as Rainer had already suggested.It's may be dangerous to run the navicli commands unknowingly or without engaging EMC Support.My $0.02 Thanks,Sandip
