Specifying the IOEPRMxx concatenation

To concatenate data sets to the IOEPRMxx concatenation, you specify the suffixes of the IOEPRMxx data sets on the PARM option of the FILESYSTYPE TYPE(ZFS) statement in the BPXPRMxx parmlib member (see BPXPRMxx (z/OS UNIX System Services parameters)). The PARM parameter is case sensitive; you must enter the string of suffixes in upper case. Figure 1 shows an example of a FILESYSTYPE TYPE(ZFS) statement.

Figure 1. Example: FILESYSTYPE TYPE(ZFS) statement

FILESYSTYPE TYPE(ZFS) ENTRYPOINT(IOEFSCM) 
ASNAME(ZFS,'SUB=MSTR') 
PARM('PRM=(01,02,03)')

You can specify any system symbol in the PARM parameter that resolves to two characters. For example, Figure 2 shows a FILESYSTYPE TYPE(ZFS) statement that uses system symbols.

Figure 2. Example: FILESYSTYPE TYPE(ZFS) statement using system symbols

FILESYSTYPE TYPE(ZFS) ENTRYPOINT(IOEFSCM) 
ASNAME(ZFS,'SUB=MSTR') 
PARM('PRM=(01,&SYSCLONE.)')

If symbol &SYSCLONE is equal to AB, this statement specifies that the system should search parmlib member IOEPRM01 first and IOEPRMAB second. You might use this specification if, for example, parmlib member IOEPRM01 contains common configuration options and IOEPRMAB contains configuration options specific to system AB. If the system does not find a particular parmlib member, the search for the configuration option continues with the next parmlib member.

You can specify up to 32 IOEPRMxx member suffixes in the PARM parameter. To specify 32 members, type member suffixes up to column 71 and then continue them in column 1 on the next line. For example, Figure 3 shows an FILESYSTYPE TYPE(ZFS) statement that specifies 32 IOEPRMxx members.
