I have not experimented with this much, since we use SYSRES volser as part of the filesystem datasetname. But, I'm still trying to fathom if ZFS indirect volser support would even work in a multisystem sysplex with Sysplex filesharing? If I have LPAR A on SYSRESA, and LPAR B running on SYSRESB, both with a root filesystem residing on the SYSRES called OMVS.ROOT cataloged in the same master cat with a symbol of &SYSR1. It would seem like Unix would kick this out in error thinking it is the same filesystem mounted at two different locations in the hierarchy /$VERSION/
Additionally, in a simpler environment how would one mount the OMVS.ROOT+others associated with your SMPE environment at presumably /Service on the same system that has OMVS.ROOT mounted at /? Sounds like you would have to have a different filenames for maintenance anyway. In my environment, the maintenance environment is never IPL'd, and the traditional datasets(non-ZFS) are not cataloged. Unless I am missing something, while handy for maybe a subset of folks, ZFS indirect cataloging doesn’t seem to buy much, and in fact maybe make things more confusing. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Donald Likens Sent: Tuesday, January 14, 2014 5:11 PM To: [email protected] Subject: zFS Indirect volser support OK I already figured out that the following command allows a shop to use indirect volser support for zFS files. DEFINE CLUSTER (NAME(ZFS.ROOT) LINEAR VOLUMES(&SYSR1) RECATALOG) I also figured out that (at least on z/OS R12) that you cannot use a 6 character symbolic and you cannot use ******. It says in the IDCAMS manual that the cluster must be defined in the VVDS. So my question is how does this really help? When I attempted the command and the VVDS did not exist on the volume I got an error message indicating that it could not find the cluster. This kind of made since but I am looking to keep the Root on the SYSRES. So do I need to re-catalog the entry on every IPL so that it reads the VVDS? If so I guess the only value is that you can move from one master catalog to another master catalog. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN This e-mail transmission contains information that is confidential and may be privileged.
