Function
This command is a TSO/E command called from REXX scripts.
Storage system information about the specified volume is obtained from the storage system, and
stored in the device information structure specified by the STEM parameter. For a copy pair, you
can specify this for either the P-VOL or the S-VOL.
If the specified volume is not found, or storage system information cannot be obtained due to an
I/O error, an error message is created in the message structure, and a nonzero return code is
returned.
Parameters
STEM(stem-name- 1 ) ~ <REXX prefix of 64 or fewer characters>
Specify an optional prefix for the name of the device information structure in which the storage
system information is stored. You must also include a trailing period character.
SN(storage system-serial-number) ~ <from 5 to 12 alphanumeric characters>
Specify the serial number of the storage system to which the volume obtaining storage system
information belongs.
When this parameter is specified, the route list needs to be loaded before the command is executed.
CU(cu-number) ~ <2-digit hexadecimal number>
Specify the CU number of the volume for obtaining storage system information.
When this parameter is specified, the route list needs to be loaded before the command is executed.
CCA(cca-number) ~ <2-digit hexadecimal number>
Specify the CCA number of the volume for obtaining storage system information.
When this parameter is specified, the route list needs to be loaded before the command is executed.
DEVN(device-number) ~ <4-digit hexadecimal number>
Specify the device number of the volume for obtaining storage system information.
This parameter can only be specified for locally connected devices. It cannot be specified for Non
Gen'ed volumes.
MSG(stem-name-2) ~ <REXX prefix of 64 or fewer characters>
Specify an optional prefix for the name of the message structure used to store the messages to be
generated by this command. You must also include a trailing period character.
The message structure is initialized when the CLI command with the same name as the MSG
parameter is specified.
PATH
Specify this parameter to obtain information on inter-CU or inter-DKC logical paths. If this parameter
is specified, the command obtains information on the inter-DKC logical paths that are established
from storage systems to which the volume specified by the DEVN parameter or the SN, CU, and
CCA parameters belongs. Additionally, the command also obtains information on inter-CU logical
paths established from CUs to which this volume belongs. The obtained information is stored in a
path set structure whose name begins with stem-name-specified-in-STEM-parameterPATH.
SSN(serial-number) ~ <from 5 to 12 alphanumeric characters>
To obtain information on an inter-DKC logical path, specify the serial number of the secondary
storage system for the inter-DKC logical path you want to obtain. You can obtain information on
inter-DKC logical paths whose primary storage system to which the volume specified by the DEVN
