Finally I have finished wading through the HSM starter set and customized it the way we want to use it - just migrating to ML1, no ML2, no backup, no recovery, no dumping, no tapes, a really minimal environment. That means I only start DFHSM with an MCDS (OFFCAT, BAKCAT, JOURNAL, ARCLOGX, ARCLOGY, ARCPDOX and ARCPDOY all set to DUMMY). According to the Implementation&Customization Guide, all of the dummied data sets are optional, even if some of them are 'strongly recommended'.
After starting DFHSM in this really minimal config, I unfortunately get several errors: *ARC0035E DFSMSHSM JOURNAL IS PERMANENTLY DISABLED, ARC0035E (CONT.) REASON=4 (DD DUMMY specified) yes, this is intentional. Why is this an error? Journaling is optional according to the books. *ARC0860E JOURNAL SPACE MONITORING DISABLED - RC=24. 094 ARC0860E (CONT.) MIGRATION, BACKUP, FRBACKUP, DUMP, AND RECYCLE HELD. RC24 says "Backup control data set or journal is not being used by DFSMShsm." - yes, we don't want to use the backup function! And the book explicitly says that neither of the two data sets are *required* if all I want to use are space management functions. Unfortunately this looks like I won't be able to use HSM at all, since migration is also held. Am I correct in assuming that the books are wrong and even for my minimal needs a BCDS and/or journals are *required*? ARC0945I OPEN OF DDNAME= >0 FAILED, VSAM REASON ARC0945I (CONT.) CODE IS X'00' *ARC0134I BACKUP CONTROL DATA SET NOT OPENED, BACKUP ARC0134I (CONT.) WILL NOT BE ENABLED ARC0945I OPEN OF DDNAME= § >- FAILED, VSAM REASON ARC0945I (CONT.) CODE IS X'00' ARC0133I OFFLINE CONTROL DATA SET NOT OPENED, TAPE ARC0133I (CONT.) SUPPORT WILL NOT BE ACTIVE Great. Don't you just love it when a simple DD DUMMY results in these messages? (I just love ddnames >0 and § >-). At least these are only informational messages, so I can ignore them. Then HSM reads my ARCCMDxx member and comes back with ARC0103I INVALID SETSYS PARAMETER TAPEMIGRATION for this statement: SETSYS TAPEMIGRATION(NONE) I don't see the problem with this statement, why is it invalid? I shut down HSM again, and it was started with SETSYS PRIMARYSPMGMTSTART (0000 0000) to begin with, so hopefully it did not do anything just yet. I also got this message: *ARC1901E NUMBER OF VOLUMES ELIGIBLE FOR ON-DEMAND ARC1901E (CONT.) MIGRATION HAS REACHED 00004 which I don't understand. I have exactly 4 volumes that are SMS-managed and I don't want HSM to touch any of my non-SMS volumes (no addvols for any other volumes defined). The ODMNOTIFICATIONLIMIT is set to 4, so I guess that is why I got that message. I still don't understand why I got it at all, though, since there was certainly nobody issuing hmigrate commands anywhere on our system. Assuming that that is what 'on-demand-migration' means (or did I get that wrong, too?) I guess my main question is: Will I be able to migrate data sets after having gotten ARC860E?
