Thanks for pointing this out Ed. I agree with the other responders that Single Object Operations what is implied here.
More interesting though is the recommendation to use this method. I suppose a change has been made in z/OS 1.8 as I've always seen it recommended that to CF the CHP offline to the OS and only use this technique as a last resort. Does some release of zVM play nicely with this technique? Alan As a software developer, doing part time sysprog work, I will yield to the expertise on this forum to set me straight on system programming matters. Here's my latest puzzler: "z/OS V1.8 System Commands" contains the following in the discussion of the CONFIG CHP command: <IBM Documentation> Note that if you have systems running on a processor at the z990 level or higher, you can automatically reconfigure channel paths on and offline using the hardware management console (HMC) instead of issuing the CONFIG command. On a z990, you may have multiple logical channel subsystems, which means that if an ESCON card fails, you need to reconfigure 15 channels being used across 30 different partitions in each logical channel subsystem. Automatic CHPID reconfiguration lets you issue a reconfiguration request centrally from HMC, which in turn triggers the z/OS systems in each partition to issue the CONFIG command. Then only those partitions that cannot process the request or are not running on a z990 level processor or higher need to be individually reconfigured with the CONFIG command. </IBM Documentation> This seems to imply that I can configure a CHP offline for the CEC (or maybe for a CSS?) at the HMC and all of the attached LPARs will automatically take action. Sounds great! The only problem is, I can't figure out how to do it on my new z9BC HMC. Of course, it's always possible that I'm just thoroughly confused about what's being described in the book. On the HMC, under "Operational Customization", I have "Configure Channel Path On/Off". When I drag the CEC to the icon, I get the following error: "Object is not an acceptable type of object for the task" I can drag "CPC Images" (or any group of Images) to the icon, and get a list of the LPARs in the group. The instructions in the dialog box say, "This task can only be performed with a single target object". Indeed, only one LPAR may be selected at a time. So what am I missing? Where's the new functionality? How is a one-at-a-time, by LPAR, request from the HMC better than a one-at-a-time, by LPAR, CONFIG command? (How is it any better than RO *ALL,CF xxx across a sysplex?) Is there something I need to enable in my IODF, IOCDS, HMC, or SE to make the functionality worthwhile? Any clarification will be very much appreciated. ---------------------------------------------------------------------- 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
