How to enable FAST Cache on multiple LUNs/MetaLUNs

Looking thru the NaviCLI admin guide, i cannot find any CLI commands that you can script to enable cache on a lun.  So it looks like the GUI might be the only place to enable it

Are you able to highlight a few lun's and select properties and then enable it?  Make sure they are normal lun's and not a metalun.  you cannot edit properties when selecting multiple metaluns

Unfortunately there is not an option to enable FAST Cache on a MetaLUN basis.

You can perform a show component luns on the MetaLUN and then enable FAST Cache on a per LUN basis. The GUI does not allow me to highlight multiple LUNs, select properties and then enable FAST Cache all at once.

I believe there must be a better way of doing this as this simply is not practical on a storage system with even 100+ LUNS

tools/suggestions/options anyone

While there is no command as such to enable FAST Cache on multiple LUNs at the same time, the Secure CLI does support enabling/disabling FAST Cache. See FAST Cache whitepaper on Powerlink.

Ok.

I did some more research and found that basically what I am asking is not possible, however there are NaviSECCli commands that can be used...

The commands look good enough for me to script this and come up with my own solution.

Thank you to all who contributed and I will split points accordingly

I was actually looking for a solution for the same problem. I found this post but no command mentioned. Here is how i am doing it.

To get the status of FastCache on a LUN...

# naviseccli -h getlun -fastcache

FAST Cache :             Disabled

FAST Cache Read Hits:    0

FAST Cache Read Misses:  0

FAST Cache Write Hits:   0

FAST Cache Write Misses: 0

To enable the fastcache on a Raidgroup LUN:

# naviseccli -h chglun -l -fastcache 1

To Check the status of FastCache again after enabling.

# naviseccli -h getlun -fastcache

FAST Cache :             Enabled

FAST Cache Read Hits:    0

FAST Cache Read Misses:  0

FAST Cache Write Hits:   0

FAST Cache Write Misses: 0

I have about 89 LUNs  to enable fastcache hence i am going to script the activity.

The following doc on emc powerlink helped me to achieve my goal.

I know cxguy figured what to do. Reason for my posting is to help anyone who may be looking for help.

Indeed, chglun has the option.

I'm wondering if we can change the FAST VP Pool LUN with chglun to enable/disable FAST Cache on that particular Pool LUN???

And I found almost every where people/guide state we can enable/disable FAST Cache on FAST Pool basis, but not Pool LUN individually.

correct FAST Cache can be managed individually for traditional RAID LUNs only.

not on a pool LUN, on traditional raid LUN yes.

Thanks for your answers. My understandings are correct.
