Hi Allan, I issued the command - HSEND RECYCLE ALL EXECUTE PERCENTVALID(0) - but HSM didn't release the tapes. In this LPAR these tapes belong to a dedicated HSM pool. Would you hazard a guess as to why the tapes still show when I issue the LIST TTOC SELECT(BOTH) 020052 3590-1 ML2 0098302500 0000000000 000 EMPTY NO *NONE* *NONE* 020053 3590-1 ML2 0098302500 0000000000 000 EMPTY NO *NONE* *NONE* 020054 3590-1 ML2 0003932100 0000000000 000 EMPTY NO *NONE* *NONE* 020055 3590-1 ML2 0098302500 0000000000 000 EMPTY NO *NONE* *NONE* 020056 3590-1 ML2 0098302500 0000000000 000 EMPTY NO *NONE* *NONE* 020057 3590-1 ML2 0098302500 0000000000 000 EMPTY NO *NONE* *NONE* 020059 3590-1 ML2 0098302500 0000000000 000 EMPTY NO *NONE* *NONE* 020065 3590-1 ML2 0098302500 0000000000 000 EMPTY NO *NONE* *NONE*

As long as the tape is marked "full" it will not be available for DF/HSM reuse. You might also want to verify the settings for SETSYS TAPEDELETION. A bit of history here: In the early days, there was a concept of DF/HSM "ownership" of tape volumes. The concept still exists, in the fact the you must take a specific action to release a backup or migration volume. Dump tapes need no special action. If you *are* using DF/HSM pooling, these tapes should be undefined/ignored,... by your tape management system. Note: I am not advocating the DF/HSM pooling. I would much rather have the tape management system handle them via the EDM interface). HTH, <snip> I have noticed this strange oddity about HSM, we have several tapes with 0 files on them as shown by the TTOC. : VOLSER UNIT VOL REUSE VALID PCT VOL RACF PREV SUCC NAME TYPE CAPACITY BLKS VALID STATUS VOL VOL 030103 3590-1 ML2 0005521900 0000000000 000 FULL NO *NONE* *NONE* NUM ONE ALT LIB STORAGE REC FILE VOL GROUP 001 *** *NONE* *NO LIB* **NO SG* * </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
