CA-Vantage SMSROUTE in a GDPS environment

[Lawrence Bulley]

​We run a GDPS environment and we want to use ADDOVRP to automatically add volumes into storage groups.  Our system programmers do not want to use System Group Names and prefer that we use a system symbolic.

Is it possible for an enhancement for SMSROUTE in VKGPARMS to use a system symbolic?
For instance, in IEASYM00 code SYMDEF(&NK_.=LPR1,LPR2,LPR3,LPR4), and in VKGPARMS code SMSROUTE (&NK_.)?

We cannot use SMSROUTE (*ALL), as the disks must not be varied online to our GDPS K-Lpars.

it is a good idea to have this possibility.
thanks and Regards, adriana

Hello Lawrence,

It is true that today the SMSROUTE value length is of 4 characters and so you have troubles to use symbols.
However, even if it is not nice, you can get it working.

I tested today with the symbol defined as follow:

SYSDEF SYMDEF(&L_.='ABCD') 

The result after refresh is good:

SMSROUTE | &L_.                                           | ABCD

So that means that you will have to have a unique character to differentiate the Lpars from each others. I think that you can use it like that for now.

On another hand, we should review the possibility to increase the SMSROUTE length size when the first character is an ampersand(&) as we will have a symbolic substitution.
This is a very good idea, thank you.
I will let our Vantage team to provide an update on this request.

Have a try with my solution and let me know.

​Hello Pierre,

I think that you have missed my point.  We have many Lpars in a GDPS environment (with K-Lpars).  If we defined a system symbolic with more than one Lpar and then define SMSROUTE as that symbolic, CA-Vantage only picks up the first Lpar in the symbolic list -

SYMDEF(&K_.=LPR1,LPR2)
SMSROUTE | &K_.                                           | LPR1

We need to have SMSROUTE pick up all Lpars defined in the system symbolic, so that the VARY command that is used by ADDOVRP is routed to all of those Lpars.

Regards,

Lawrence

​Another, possibly easier to implement, solution, would be to allow the system symbolic to pass through and allow the operating system to do the substitution, like so -

SYMDEF(&K_.=LPR1,LPR2)
SMSROUTE | &K_.                                           | &K_.

Regards,

Lawrence

Hello Lawrence,

Thank you for the clarification that I do not catch at first read.
So Vantage is linked to the Lpar where it is running and so do not have access to other Lpars. That means that what you are asking for needs to be reviewed as an enhancement request and valued for its feasibility or not.
I will let our Product Owner review and answer to you.

Have a nice weekend.
Regards,
Pierre
