How to Shut Down CX320 ?

Jump to solution

 

We want to gracefully shut down our two SANs tomorrow afternoon to allow for a scheduled power outage.   We've checked Navisphere Help and it does not cover this.  Nor does any online material we can find or the Navisphere documentation.  Navisphere either can’t do it or has it very deeply buried.

 

Can you let me know how I can go about shutting down a CX-320 / 300 gracefully ?  We’re using Navisphere v6.19.3.4.0.

 

Your help would be really appreciated emoticon.Wink.title

 

Thanks.

Steps to shut down an EMC CX-array with dual SPSes:

- shut down the servers that use storage on the array

- wait 5 minutes (to let the cache be written to disk)

- power off the SPSes

- wait for the SPE (CX3-20) or DPE (CX300) to power down

- power off any daisy chained DAEs

- if you have switches, you can now power those down too

- if you have any fiber connected tape libraries, you can power those down too

 

More importantly is the power up procedure:

- power up the switches

- power up the DAEs (other than the DAE-OS as that's powered by the SPS)

- power up any tape libraries you may have and wait 2 minutes

- power up the SPSes and wait 5-10 minutes till the storage processors have finished booting (verify by pulling up Navisphere)

- power up the servers

On a power up it is normal to see the SPSes charging, and until 1 SPS has finished charging, write cache will be disabled. While the write cache is disabled you can already use your servers/storage, but it will just be slower till the write cache enables.
