DFHSM PROBLEM - ARC0560E
I am trying to resovle the problem of ARC0560E - ARC0560E MIGRATION LIMITED: NO MIGRATION LEVEL 1 SPACE AVAILABLE At 01:40 I issued the command to change the threshold of the ML1 vols to 90 Later, I issued the command at 02:05 to start SECONDARY SPACE MANAGEMENT: HSEND SETSYS SECONDARYSPMGMTSTART(0200 1000). However when I do a HSEND Q AC it doesn't show that it kicked in. I also checked the STC for the message : ARC0517I SECONDARY SPACE MANAGEMENT STARTING but nothing shows. I reissued the command at 02 20: HSEND SETSYS SECONDARYSPMGMTSTART(0230 1000) Still nothing. Is there something else I should do? -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

First of all, lower your ML1 Thresholds to 50. Raising it to 90 prevents the volume from being eligible for migration to ML2 until it is 90% full. Second, how many ML1 volumes do you have? If 10 or more you might consider issuing a Freevol against the one most fragmented. ex. HSEND FREEVOL MVOL(HSM129) TARGETLEVEL(ML1) Use ISMF panel 2;1 to obtain list of ML1 volumes. That will tell you the Fragmentation Index You might have to issue a Q AC and determine if Migration is HELD, if it is Release it. Or you could simply take a spare volume and addvol it to your ML1 pool. Don't forget to add the addvol statement to your parmlib.

Re: DFHSM PROBLEM - ARC0560E
HSM uses a 24 hour clock. Were you really doing this at 2AM in the morning? Did you issue a Q AUTO to see if any tasks are held? If so, you can issue a RELEASE ALL. -Original Message- From: willie bunter [mailto:snip] Sent: Saturday, June 07, 2008 12:02 AM To: IBM-MAIN@BAMA.UA.EDU Subject: DFHSM PROBLEM - ARC0560E I am trying to resovle the problem of ARC0560E - ARC0560E MIGRATION LIMITED: NO MIGRATION LEVEL 1 SPACE AVAILABLE At 01:40 I issued the command to change the threshold of the ML1 vols to 90 Later, I issued the command at 02:05 to start SECONDARY SPACE MANAGEMENT: HSEND SETSYS SECONDARYSPMGMTSTART(0200 1000).

Re: DFHSM PROBLEM - ARC0560E
David, I apologise for not acknowledging your post earlier. I was off work due to an illness. I solved my problem by invoking Secondary Space Management. The reason why it was not running initially was because it was not scheduled to run on a Saturday. I altered the parm to YYN and it worked. There are 18 ML1 vols and all were full which prompted the Primary Space Management to fail this is why I was trying to execute the SSM. I have taken note about your suggestion to lower the threshold from 80% to 50%. Thanks to all who helped me out. --- On Sat, 6/7/08, O'Brien, David W.
