Brian, What datasets do you mean by "IPL datasets cataloged to &SYSR1"? Everything on my SYSRES is cataloged to &SYSR1 except SYS1.PARMLIB and we IPL just fine. According to the 2.2 INIT & TUNING manual, changing &SYSR1 is not allowed in IEASYMxx at all. The further documented restriction is that SYS1.PARMLIB cannot use &SYSR1 nor can any dataset defined in the LOADxx member being used unless the LOADxx member also has the vol-ser defined therein so the system can find it.

The same is true if you try to use a symbolic for the catalog volume(s) (assuming it's separate from the res volume(s)), but I think that issue is the ICF catalogs themselves. You can however catalog normal non-vsam datasets to any symbol you want so long as you identify it in the IEASYMxx member. I ALWAYS catalog ALL my DLIB and some VENDOR volumes that way, it makes life (and maintenance) a lot easier to be able to change the volsers. (i.e. one of the sites I manage has their current IPL vols as is C23RS1 (which has every cataloged as ******) , C23RS2 ( which has everything cataloged to &SYSR2) and C23DL1 (which has everything cataloged to &SYSDL1) , C23DL2 (same format but &SYSDL2) and C23DL3 (same format but &SYSDL3), and the next one will be D23RS1, and D23RS2, D23DL1, D23DL2 and D23DL3. There is no re cataloging of datasets necessary, I just change the IEASYMxx member and everything is where it needs to be. My Backup SYSRES's are C23RSA and C23RSB and again, I just point the IPL to C23RSA and IEASYMxx is changed to point &SYSR2 to C23RSB and everything is set yo IPL and go. The names of the volumes themselves can be whatever I want to make them easy to remember in an emergency, they could be 111111 and 222222 and the process would be the same. It's very easy to do maintenance this way.
