create logical disk, MVS SSID(in hex)

Question

Need answer to what used to be a simple question. It's been a while, I remember putting something like FF in the field, but it's fuzzy and this is not a toy...so you know. MVS SSID (in hex) field. What goes there? I'm using the lgoical device configuration in ECC 5.2. I've got all the parameters, and I have about 2T in usable unconfigured capacity, and I'm wanting to use some of it for a few new volumes. Any help would be appreciated. BTW, this is for open systems.

looks like you have a bunch of slots available. I do not know how to specify ssid when you map in ECC but if you were to do it via cli, your configuration file would be:

create dev count=40, size=18414,emulation=FBA,config=2-Way-Mir disk_group=5 mvs_ssid=2;

Sub System ID : 0x0002
Maximum Number of Devices Allowed : 256
Number of Devices Currently Present: 22

subsystem id 2 has plenty of empty slots ..so that's what i used in example above. Modify number of devices, size, disk_group and config according to your needs.

Do you have MVS connected to the same array? If not you don't need to populate this field. If so, you will need to check what MVS_SSIDs are already in use and how many "slots" are available in the existing ones.

I just heading out for lunch, but if no one has added to this by the time I get back I'll dig up the commands on how to view existing SSIDs and their utilization.

Yes, I have an mvs....but I remember in the past populating the field with hex F's(though I don't remember how many), and thus it selected the next available...It was a shortcut from an engineer.

If you have the info though, i'd of course be happy for it.

Thanks
