suggest me on emc storage shutdown/power on steps
Hi All,
We have EMC Celerra NX-4 (Backend Clariion AX4-5F8) Storage box. please find the attached rack mounted setup and find the storage shutdown and startup steps which i did last week for maintenance. please suggest me power down/up steps whether right or not.
Shutdown:
First shutdown SP-A and SP-B through Navisphere manager. (navisphere manager version: 6.28.0.4.32)
Shutdown the Celerra server through CLI
- $ /nas/bin/nas_checkup
- # /nasmcd/sbin/nas_halt now
Data mover power removal
DAE (disk array enclosure power removal need)
Power on:
Power on all DAEs
Power on SPA. If SPA on , then SPB automatically up
Data mover power on
No Events found!

Hi Dhakshinamoorth,
as far as i know the nas server should be powered down first.
After that power down the SPs, followed by the DAEs.
Powering up seems to be ok.
Cheers,
Sascha

Hi Sascha,

You don't have to login to Navisphere for shutting down SP. You can power ON control station, login and ensure the data movers are OFF (/nasmcd/sbin/getreason). Then you can enter the halt command once again to power down the NAS components (C.S). Once done, you can power OFF storage (power OFF the SPSs at a time. once both the SPs are OFF, you may power off all the other enclosures).

Hi Vipin,
As per your comment, when we shutdown the storage processor by power off SPS switch means, SP-A and SP-B windows XP Embedded machines powered off abruptly? or it is graceful shutdown?

It is the way to shutdown a clariion. You may refer to the procedure generators also for the same. I hope the Embedded XP will be getting shutdown command and will go for a graceful shutdown.
