va7100 proper process for shutdown?

[mike_s_brentlinger]

probably just going to show my stupidity here... but is there a 'offically proper process' to down a va7100?

http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=217132&admit=-682735245+1153922272056+28353475

seems to indicate i should down my hpux box attached and then thru one of the va7100s controllers serial port issue a 'shutdown > shutdown>' so that maps are flushed to the map disks (and data from cache) to be safe from battery failures.

otherwise i can just press the power button or cut power and the maps should be saved within the cache which is backed up for approximately 5 days via battery...

i have new batteries in the va7100 and armdisp shows my batteries are ok. but im not one to be risky if not needed and would like to down this thing as safely as possible.

i connected a laptop to the serial ports labled rs232 on the back of the controllers but got nothing thru minicom so im not certain what kind of console i should be getting.

i do have a va7100 shell with no drives and one contorller here but when i console into it and try to power it up to fool with it i just get a 'not enough drives' error so i cant really use it as a test to toy with. i do think though that the fact that i get some text from that va7100 shell means my minicom session, serial cable, etc are all setup right so im not sure why i dont get a console on the other live va7100 that i need to shutdown gracefully.

anyone have any insights? thanks very much ahead of time.

You can also stop your application that access the VA, deactivate the VGs and run

armmgr -s shut

Regarding the serial connection:
Try to use hyperterminal with a connection speed of 9600 - this should work.

You should get a prompt like

READY>
or
Warning State >

gotcha; my consoel issue was hardware/software flow contorl needed to be off.

now i get a
READY>

so in theory id down my attached hpux box, then issue a "shutdown,shutdown" at that ready prompt? does it matter which controller I issue this on or should I do both?

forgive me... ive searched and searched for some technical documentation and cant find it, if youd rather just respond with RTFM i understand, but if so could some kind soul point me to where i could find the manual first :/

Here it is:

http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00300020/c00300020.pdf

You need to search for "command view sdm" in drivers and software download section on www.hp.com and follow the link to the manuals. I know it's not easy to find.

Here are manuals about the arry itself

Ah thanks for the doc links, the command view sdm guide will certainly be helpful. Though I still fail to see docs on the contorller console.

Anyway more fooling around yeilded me the following at the console:

Ready > mgr -?
Performs subsystem management operations.
Usage:
mgr -s {shut | start}
mgr -R {full | partial}
mgr -B {autoraid | raid1}
mgr -O {on | off}
mgr -ds {on | off}
mgr -p {on | off}
mgr -L -c
mgr -q
mgr -os -c
mgr -t -c
mgr -S -c
mgr -V
mgr [-?]

-s : Shutdown or Restart the subsystem.
...
...
...

It seems a "READY> mgr -s shut" may be what I want on each controller after downing the HPUX box thats attached to the VA

[Torsten. · Accepted solution]

You are right,

"READY> mgr -s shut"

will shutdown the array. You need to issue the command on only 1 controller.

good deal.. thanks much for your insights and assistance.
