Hi Waheb, I do not have this PTF installed.
Yes we are using HYPERPAV. We have shared DASD between our z/OS and z/VM LPARs. If I turn off HYPERPAV on my z/VM LPAR via the SET command, will that also turn off HYPERPAV effectively on the z/OS side for those volumes on that CU ? I don't want it to affect the z/OS side. If it does affect z/OS then my only option would be to apply the PTF. Thanks.

It is on the 1002 RSU. Are you using HYPERPAV? If so, removing HYPERPAV volume use from your VM LPAR should resolve the problem. We had similar problem and the applying 1002 RSU service fixed it. Example: 1. Q CU 0039 PAVMODE If it is in any kind of PAV mode then: 2. SET CU NOPAV 0039 3. RUN your test. Hope this helps!

We are running z/Linux under z/VM 5.4 Redhat 5.4. My zLinux Admin were doing compares between the production environment versus the Test D/R environment and noticed it. He issued the following on the prod zLinux guest environment: # mount -o remount,rw /dev/VolGroup01/LogVol00 mount: block device /dev/VolGroup01/LogVol00 is write-protected, mounting read-only Since we are testing our D/R process at the moment for the z/VM LPAR we are unsure at this point whether that is a contributing factor. It should not be but we can't rule it out. We paused our PPRC/Global mirroring from the z/OS side before starting the D/R activities to perform recovery of the z/VM & z/Linux. The problem was found while in the middle of verifying/comparing environments on the zLinux side. I can link to the minidisk that is used to IPL that zLinux guest and it shows R/W when I issue Q LINKS. All other minidisks owned by that zLinux guest are R/W as well. From my perspective (z/VM) all looks good. Any input would be appreciated, if anything to rule out that PPRC/GM would have contributed to this. Thanks. Steve. ****************************************************************************************** This message may contain confidential or proprietary information intended only for the use of the addressee(s) named above or may contain information that is legally privileged.
