can't create vdev on dmx4
Hi,
I have DMX4-24/5773. Few days ago I've created few vdevs, but today I need much more of them ( ~250 ).
I've tryed with count 220, 10 and 5, but get error below:
$ symconfigure -sid xxxx -cmd "create dev count=5, size=29491 cyl, emulation=fba, config=vdev;" -v comm
Execute a symconfigure operation for symmetrix '000290103837' (y/ ) ? y

}

The configuration change COMMIT failed. Please see the SYMAPI log file for more information

Terminating the configuration change session..............Done.
The configuration change session has failed.
In symapi log we have few minutes repeating:

Can anyone help?
we have some snap sessions already active, so vdevs can be created...
Regards

There can be a multitude of reasons for the configuration change failure. The API log will only provide part of the answer, please open a Service Request with the Symmetrix Support Center for further investigation.

I guess its a script which is stuck. PSE will need to recover it by dialing in to the box.

I know that command is ok, I run it few weeks ago, when I created some vdevs.
Is there some commands to see "system readynes" or something?

There is nothing wrong in the command, please review the symapi logs, and open a case with EMC.
I have tested your commands, and i got 5 new vdev's. There may be some scripts malfunctioning or something else... its better to check with PSE.

The prepare does't for you, it does verifies the array readiness. The commit does include the prepare and fails, if the array is not ready. Most of the time the preview will pass, but it will fail at commit.
symconfigure -sid xxxx -cmd "create dev count=5, size=29491 cyl, emulation=fba, config=vdev;" -v prepare

no locks at all.
$ symcfg list -lock
S Y M M E T R I X L O C K S
Lock Lock Lock Time
SymmID Attachment Status Number Usage Held (Sec)
0002xxxxxxxxx Local N/A N/A N/A N/A
$ symcfg list -lockn all

Is it possible that there is to less cache on sym box:
$ symcfg list

You've tried a symcfg discover first, also you can see if you have any lock in symmetrix:
symcfg list -lock
symcfg list -lockn all

could be a hot spare process running, until it finishes can't do any changes. I get that often on our DMX4.

but ecc basicaly use solution enabler to "talk" with symm.
Maybe to remove /var/symapi/db/symapi_db.bin and do the symcfg disc again?

You can to rename symapi_ db for symapi_db.old.

For the answer of dynamox, you can check:
symdisk -sid xxx list -failed -v

symdisk does not always show failed drives. I have seen many instances where ECC will report drive failure and hot spare kicking in, yet symdisk says everything is ok.
