Re: maintaining PARMLIBs over several sysplexes
We have one parmlib for all our LPARs (actually 2, one for prod lpars, one for test/install/sandbox lpars). We try to keep the contents of the members equal for all LPARs and specify differences b.m.o. system symbolics. To facilitate this as much as possible, we added a number of system symbolic to the different LPARNAME sections of IEASYM00. E.g. if LPARX runs Subarea 50 and LPARY runs Subarea 51, we specify &SA in the parmlib members and the &SA system symbolic in the MVSX and MVSY LPARNAME sections of IEASYM00.

Re: ICSF Question
If you just want a list of the key labels, then a 'PRINT INDA('ckds name')
COUNT()' will probably work, if you have read access to the keystore. (Be
careful and see below.) If you want something to format the flags and fields
in the record then you can do that either processing the data thru the ICSF
APIs or directly reading the VSAM file. I've got REXX EXECs but they are not
very comprehensive. I use the RXVSAM package from the CBTape to read the VSAM
record and then display specific fields.
The problem is that in most shops, the CKDS contains clear keys, and anyone
that has authority to read the keystore can also see the actual key value of
those clear keys. (The secure keys are encrypted under the master key, so that
key material is protected.) I recommend that only the ICSF address space
should have authority to the keystore.
In addition, if you use the APIs, then the application must run APF authorized
to process a clear key.
The last several releases of ICSF have introduced a number of enhancements
related to key management, so I suspect that somebody, somewhere is working on
a key management tool (or set of tools) that will provide details about
existing key records. Since key management is the hard part of crypto, such a
tool is sorely needed.

Re: Question on an HMC's ethernet adapter

I am able to access the HMC itself remotely so that connection is good, but the connection to the HMC-SE LAN is the one that is failing, as I cannot access SE functions, such as single object operations from the HMC.

Some older HMCs had Ethernet cards and the 'newer' ones have Ethernet ports built-in the motherboard of the HMC PC. The minimum info the SR would need is the Machine Type and Model of the HMC e.g: -123. This is important as over time, like all x86 PCs, these are 'refreshed'. Your z9 HMC may have come with the System or even be an older one if the z9 was upgraded from a prior generation. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
Re: Question on an HMC's ethernet adapter
It depends on your HMC PC model. Some older HMCs had Ethernet cards and the 'newer' ones have Ethernet ports built-in the motherboard of the HMC PC.
