MSA1000 safe poweroff?

[Michael BUTOW]

Hi all

How do I safely power off a MSA1000 system?

Regards,
Michael

You shutdown the servers and then press the power button on the MSA. :-)

[Michael BUTOW]

We have shutdown the servers connected to the MSA1000, but after this, some hard disk activity is still indicated on the MSA1000.

Is there a way to ensure that the caches etc. on the MSA1000 are flushed and the unit is ready for poweroff?

[Bostjan Kosi]

The only thing is to check the ACU for any exra activity like rebuilding and so...otherwise...you can also power off and power on again and check the info on the display... BTW the batteries should hold data for aprox 4 days...so..no worries...

What you are seeing is the Surface Scan running. If you notice the bottom right row of LED. If all three a lit then, the cpu isn't doing anything.

If you use the cli, you could use the
>show this_controller
This will report any unsave data in the cache.

John isn't show this_controller an HSG command? I did not now MSA is using such a compatible CLI interface...

Hi,

if you have a 'special' serial cable for MSA, you can do a miracle ;-).

BR,

* CLI> show this_controller
* Controller:
* MSA1000(c) Compaq P56350C9Ixxxxx Software 4.24 Build 272 Hardware 7

The MSA CLI implements only the barely necessary commands to set it up from the serial port.

If anyone from HP Storage is here making the CLI more user friendly would be very nice. On the HSx controllers you could abbreviate the commands. On the MSA1000 you need to type them out exactly.

On the HSx if you have a disk configured and it goes bad you get a disk misconfigured message when you do a SHOW DISK. On the MSA1000 the disk no longer shows up. If this can be more like HSx controller then so much the better.

On MSA1500 cert exam is the same question.
Good answer is: Make sure, that all host systems are correctly closed.
