Migration Path

Perform the following steps to implement ELS 7.3:

1. Install the latest ELS service on production hosts.
2. Install ELS 7.3 on test host(s).
3. Test and verify ELS 7.3 on test host(s).
4. Schedule roll-out of ELS 7.3 to production hosts.
5. Once all hosts are running ELS 7.3, then optionally convert the CDS to an I level CDS. Refer to the ELS Command, Control statement, and Utility Reference for information about the CONFIG command utility.

Note:

If VOLPARM statements are being used and the CDS is converted to an I level CDS prior to PTF L1H18AT being applied, then the SET VOLPARM utility will need to be run after the conversion. The current VOLPARM or POOLPARM information can be obtained by running the LIBGEN utility.

Create MGMTCLAS with MAXVTVSZ set to 32000 plus any other site required parameters. Refer to the ELS Command, Control Statement, and Utility Reference for information about the MGMTCLAS control statement.

Create or update SMC TREQDEF or POLICES to use the new 32GB MGMTCLAS statements. Refer to the ELS Command, Control Statement, and Utility Reference for information about the SMC POLICY and TREQDEF commands and the TAPEREQ control statement.
