Hi Listers, Two Question: 1. Environment z/OS v1.4 SMS v1.3. Running Parallel Sysplex Shared DASD between 2 sysplex 2 SMS SCDS 1 catalog We implement HSM in 1 sysplex. First phase we cutover 2 storage groups migration, backup and dump. When the dataset is migrate another sysplex show migrated. We recall from the HSM sysplex but some how in another sysplex is overwrite other dataset. Is possible or not? Please advice or if there any fix or patch?
2. In Manual z/OS v1.3 DFDSSdfp Storage Administration reference SC26-7402- 01 1.5 Running SMS in a Parallel Sysplex Environment An SMS complex consists of systems or system groups that share a common configuration. A Parallel Sysplex is made up of systems that share a cross-system coupling facility (XCF); you can run multiple SMS complexes within a Parallel Sysplex. Restrictions: An SMS complex should not span sysplexes. All of the volumes in the SMS complex should be in the same Parallel Sysplex. The cross-system sharing functions, such as VSAM record-level sharing (RLS), partitioned data set extended (PDSE) sharing, RACF(TM) security and global shared resources (GRS) serialization, only work within the scope of a single Parallel Sysplex. These functions are not supported when the SMS complex extends beyond the Parallel Sysplex in which they are carried out. Do not set up multiple SMS complexes sharing the same DASD. This requires extra work to maintain the duplicate SMS configurations and can also create problems such as running out of disk space because one configuration cannot know about changes made to the other configuration, such as data set allocations and deletions, and storage group and volume status changes. Mean we cannot shared dasd with two SMS SCDS in 2 sysplex? Please advice about my understanding. If happen like this what should I do? If need to fall back to non-sms managed in shared DASD between 2 sysplex. -- Regards, Mohd Shahrifuddin Bin Ahmad Masri Sunflower Consulting and Services Co Ltd Room 401 Minjin Xiaoyun Bldg., Block 7 Xiaoyunli, xiaoyun Road, Chaoyang District,Beijing 100016,China Mobile: (86) 1391-176-9704 Fax: (8610) 6466-1840 ---------------------------------------------------------------------- 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
