Check: ASM_LOCAL_SLOT_USAGE Comment: This one pops up regularly on LPAR's with Websphere software. It's almost impossible to keep the usage below 30%. Documentation says: "To maximize the efficiency of ASM slot management, you should keep the slot usage on all local page data sets below 30%." We're using 4 page data sets in our test LPAR's, which are ~540k tracks. Adding additional is always an option, but is it worth it? Maybe to change the warning threshold? Thoughts? >>>>>> Easy fix. Add more locals. ISTR,(although I may have missed an update) >>>>>> that there was an upper limit to the size of a local. Check: GRS_CONVERT_RESERVES Comment: Still haven't used the GRS ENQ/DEQ/RESERVE Monitor to check what reserves our systems are using. I was wondering has anyone tried to convert all RESERVEs to ENQs? Were any applications problematic? >>>>>>> There are several cases where the GRS planning manual suggests *NOT* >>>>>>> converting reserves. Check the fine manual for additional info. .....snipppage Check: XCF_CDS_SPOF Comment: For this one, I just want to confirm my understanding of the messages. I'm seeing component indicators = 30000000_00000000_00000000 on all the messages which cause this check to generate a high severity (by default) exception. By checking the DOC APAR OA28958, it seems that indicator is telling me that IBM thinks owning a single book in the CEC is a single point of failure (well, it is in some way, but... hmh?). Am I reading this right? Adding a book is defenetly not an option, so if that is the case, this one will need to stay disabled. >>>>>>> I think this is referring to both cds's on the same PU (block of 4096 >>>>>>> addresses). E.G. 8000-8FFF. I actually ignore this check. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
