We are preparing for an online migration as mentioned in the subject line. It is a 2-phases migration. For Phase 1, we do not have any SMS managed volser. DB2 groups are home-managed based on VOLSER naming convention. I wrote the following in order to prepare:
Prerequisites: A multi-tier Discovery Phase to: 1- Discover & Identify where all catalogs are. 2- Run Catalog diagnostic against all of them, and fix inconsistencies. 3- Discover & Identify where all LINKLIST are and follow Softek manual recommendation 4- Discover & Identify where all page packs are. From that list prepare new Page DSNs on -27 & prepare DRAIN commands for old ones. 5- Discover & Identify if we have any of the following DSNs, which are not supported by LDMF: 5a- VSAM data sets with the IMBED, KEYRANGE and REPLICATE options specified 5b- Catalogs 5c- ISAM 5d- Individual PDS members (LDMF does support migrating entire PDSs) 5e- Page and Swap data sets 5f- HFS / zFS data sets 5g- Data sets that are designated as "Unmoveable" are not supported, that is, DSORG=U|PSU 5h- VTOC, VVDS and VTOCIX data sets 5i- Temporary (&&) data sets 6- Discover & Identify if we have any CA products. CA product (see Softek exhibit) use UCB @ as opposed to VOLSER. As some VOLSER won't be moved online, I would like to know your suggestions on how to do all this steps ? Your suggestions for additional steps, of course, are very welcome. There are a few ways to do it with IBM Utilities, but also using non-IBM utilities. What I am also looking for are the DOs and DONTs. DONTs are much more important to me. They will save us re-run. Note: I already have done a performance assessment to identify the high-use mod-3 volser in order to avoid re-grouping them on the same -L. We are dealing with, for Phase-1, 9,000 3390-3 to convert to "possibly" 1,000 3390-L. I intend to kept high use catalog on -3. Any others ? Thanks for your help. ---------------------------------------------------------------------- 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
