Will symcfg -sid 123 -SA 7C -p 1 offline have any effect on 7C Port 0

Hi,

I have a symm with Prod Hosts connected to the Director 7C:0. We have to set SPC2/SC3 flags on 7C:1 cause it wasn't set before and the 7C:1 port was not used earlier much. Some hosts connected to it were decommed so its now free for new hosts, but the flags gotta be set before that.

My question is, if I run symcfg -sid 123 -SA 7C -p 1 , will this have any effect at all on 7C:0 ? Will they see some impact ?

Sorry if I am asking the obvious, but just want to be careful.

My SAN Management host is a Windows Host running SYMCLI 7.3

Please let me know.

no effect you will only off the single port you specify.

If this helps, the Symm is a DMX3-24  with enginuity version 5771.

it should not; Definitly wait for one more vote before you touch the production

You shouldnt need to off the port to set those flags.  If you were setting those for certain hosts you would want to reset their negotiation so they pick up those flags once they are set; a reboot of bounce of the connection will do that.

Thank you SKT, Robert Dudley and Dynamox. So has anyone done this and observed that only 7C:1 will get affected and it will not in any ways impact 7C:0 ? Please let me know.

Hi Dynamox, thanks for the replies. Yes, I can use the the hba flags option, but thing is we will have to do that every time we connect a host and I think its better setting it on the FA itself right now when I have the option.

one alternative is to use hba_flags instead of using FA flags, take a look as symmask man pages.

yes, you have to offline FAs to set those flags, did that a few months ago.

if systems connected to these FAs require pretty much same FAs ..i would do that as well.

thanks for the correction D.  I usually set them at the WWN level unless everythign needs them.  one thign we started doing was having EMC set all the flaags that may be needed and then disabling the not needed ones at the WWN level.  Most hosts seem to need most all of them now anyway.

Hi,

Thank you all. It worked fine. I am having issues now where I am not able to set the OS2007 Flag on DMX2000 Microcode 5671 with symcli 7.3. Earlier I was able to set on a different DMX 1000 with Microcode 5671  with symcli 7.1. Also able to set the flag on a DMX3 with Microcode 5771. I have opened a case with EMC and also posted the question in the forum. No help from EMC as of now.

agree, with our open systems (windows/aix/linux/esx) and default VMAX flags everything works ..the only thing that we do extra is set the "Disable_Q_Reset_on_UA" for Linux using hba_flags.
