not immediately, if you presented them and then created a file system ..then yes the pool would grab them, but if you simply present them, rescan each datamover you will see that dvols will be listed with column "inuse" having an N next to them. Then you can use that document to do whatever you want with them. Make sure that 2TB LUN is actually a couple of megabytes shy of being 2TB.

nas_disk -l

NS20 will not recognize any LUNs that are greater than 2TB (minus 2MB) in size.

When I created the two LUNs, I used the "MAX" setting from the pulldown box. Was that the incorrect thing to do?

If I add the new LUNs to the existing Celerra storage group in Navisphere, will that not automatically put them into the existing default "clarata_archive" pool?

does it apply to all systems ? Release notes only mention NS960 and select gateway systems.

Please note that the  2 TB LUN size limit for Dart is for NAS code releases prior to 5.6.44. For NAS Code releases 5.6.44 or later NAS LUN size is increased up to 16 TB.

either use MVM to build your meta's manually or create a user defined pool

both ways are described on the MVM / AVM manuals available on Powerlink or your doc CD

Good..it created ~1.8TB LUNs.

when you create FC LUNs you want to distribute them between SPA and SPB, for SATA LUNs on older Clariions it used to be best practice to put LUNs from the same raid group on the same SP, now on Celerra with CX4 it does not matter anymore. What are you trying to get to on PowerLink ..that document ? Message me privately and i will email it to you.

Please find attached documentation for managing filesystems and pools manually.  Also, you may want to review Primus emc138143.

When adding new storage to the Celerra using Navisphere (Celerra Gateway Models), a set of guidelines should be followed: On a per LUN basis there is a 2-terabyte LUN capacity limit. Therefore, it is best to create LUNs of about 1 terabyte in size, and then assign them to the Celerra, be sure to read the restrictions at the bottom of this solution.

Please note that the  2 TB LUN size limit for Dart is for NAS code releases prior to 5.6.44. For NAS Code releases 5.6.44 or later NAS LUN size is increased up to 16 TB.

After the LUNs are done binding, they can be added to the existing storage group.  Be sure to manually select an HLU / HID above 16.  After the LUNs have been added to the Storage Group on the Celerra, select rescan.  The new devices will automatically be added to the existing storage pools. (Check that the pool is set for Automatic Extension.) If the CLARiiON admin does NOT manually select a HLU / HID greater than 16, then when a rescan is conducted on the Celerra side to add this storage the following error message will appear "skipping reservered LUN id".  The devices will not be added to the Celerra database until the CLARiiON HLU / HID assignment is corrected.

Note: If LUNs are being removed from the Celerra Storage Group, then this solution does not apply. Contact the EMC support for proper assistance; otherwise data corruption could occur.

Another option to remove a LUN in NAS code 5.6 is to run the following "nas_disk -d dxx -p -unbind" which will delete the Celerra disk and auto unbind the associated LUN on the CLARiiON side.

Refer to the following document from Powerlink for additional information about this topic "Implementing Automatic Volume - Management with Celerra" - P/N 300-002-797 - Rev A03 - Version 5.5 and "Managing Celerra Volumes and File Systems with Automatic Volume Management" - P/N 300-002-689 - Rev A03 - Version 5.5.

Apparently it liked their size... they are 14 and 15 in this list.

Curiously, all the rest of the SATA LUNs defined in this system only belong to SPB and all of the FC LUNs except for one, belong to SPA. These two newly created SATA LUNs are the only SATA ones that are spread across both SPA and SPB  equally. Is this normal?  (I did not set up the system, it was installed by an EMC field engineer when it was purchased).

Also it looks like I can't download or get to anything on PowerLink right now. All I get are mostly blank empty blue screens with nothing clickable on them, lots of Java errors, and "Error on Page" messages. PowerLink was working fine for me Tuesday, I guess I'll have to call them on the phone and see what's up. I tried three different browsers on two different PCs to log in  :-(.
