Question about allocating symmetrix storage to Celerra

Question

I’ve dusted off some 4 year old notes on allocating symmetrix storage to the Celerra. I’ve set the emulation type on some devices to celerra_fba and am now trying to map these devices to the Celerra FAs. When I start this action the first thing I see is a pop-up that reads:

“For Celerra Lun address of 0x00 to 0x01 are reserved as System addresses and should not be used".

I assume this is just a warning to keep me from screwing things up. I say “ok” proceed and it puts the devices under the FA. The lun addresses are not 0x00 or 0x01. Is this message normal?

Thanks!

so you see in this example i have an available address 037, you want to make sure you find the same address on both FAs.

What is the model of your Celerra ? Does it boot from Symm ?

pzxkys · Answer

The model of the celerra is NS40g running DART 5.6.44-4. I'm not sure if it boots from the Symm. Don't think so. Not sure how to confirm that.

pzxkys · Answer

I see that the root disk is on the symm (ser. number ends in 509) :

Oh ... oops ... I see Robert slipped in an answer I hadn't noticed in the thread. okay. Thanks.

dynamox · Answer

First 10 or so lines is fine

dynamox · Answer

Is it zoned to a Clariion ?

dynamox · Answer

Can you post output from command 'nas_disk -l'

pzxkys · Answer

Thanks. Who is Robert and where do I find his recommendation?

RobertDudley · Answer

Celerra has specific requirements for lun numbers.  Data luns start an 10 (hex) and work their way up incrementally.  Lun numbers 0-F(hex) are reserved for control luns.  To find the control volumes just look for luns below F (hex) and thats where the boot volumes are.

dynamox · Answer

yep, boots from the Symm ..follow Robert's recommendation when selecting FA address for new devices.

scroll up in the thread to see what RobertDudley wrote.

Zoned to a Clariion? Yes. It's zoned to both a dmx1000 and a cx3-20.
