We use cmf instead of rmf. I had the same problem on lpar was on z/os 2.5 and 
the lpar was on z/os 2.3. We open a ticket with the great BMC and they couldn't 
figure it out for months.  So, we cross our fingers and converted the other 
lpar to z/os 2.5 and CMF started working correctly.  

Thanks

Ross,

First of all, I am glad you have opened a support case for this, our support 
team should be able to gather further diagnostic information to resolve the 
problem.

A bit of background information for the archives :

(o) In z/OS 2.4+, the SDSF "DA" information is gathered centrally by a subtask 
in the SDSFAUX address space.
(o) This subtask uses the RMF programming service ERBSMFI (GRBSMFI) to collect 
this information and any ISV product that replaces RMF supplies an alias for 
this module.
(o) The SDSFAUX address space dumps the first 256 bytes of the ERBSMFI load 
module in the HSFTRACE DD that is allocated to the SDSF started task
(o) When the RMF address space is not active, ERBSMFI still returns the data we 
require (SMF 79-1 records), however in our experience other ISV products do not 
return data when their STC is inactive and instead pass back a non-zero return 
code. As a customer for an ISV that replaces RMF, you might want to consider 
raising an RFE with them to address this.
(o) When we get a non-zero return code from ERBSMFI for 79-1 data, we fallback 
to our own internal data collector (HSFSMFI) that builds pseudo 79-1 records 
that reflect the columns that SDSF used to display prior to using ERBSMFI (many 
years ago). The SDSF client code will detect this condition and the number of 
columns shown on the DA panel will be greatly reduced from "full-RMF" function.
(o) Error conditions calling ERBSMFI are normally reflected either by WTO-style 
messages and/or messages written to the HSFLOG DD that is allocated to the SDSF 
started task.
(o) Other SDSF panels that depend on ERBSMFI include DEV and PAG, however they 
do not have internal fallback capability.

EXTERNAL EMAIL





We are currently in the process of rolling out z/OS 2.5 and have hit an issue 
on a test LPAR that is not displaying any information in the SDSF DA panels.
There are no messages in the syslog out of the IPL that would lead us in a 
certain direction.  We think we may have an issue with CMF but can't confirm.  
We are occasionally seeing error messages out of SDSFAUX as well.

It looks like beginning with z/OS 2.4 the 'SDSF DA' information is obtained by 
the SDSFAUX address space calling the BMC AMI Ops Monitor for CMF.  We have 
verified we have the CX10GVID module in our linklist library that CMF uses to 
obtain the SDSF DA values.
We have a ticket open with support as well, but curious if anyone has seen 
similar issues when rolling out z/OS 2.5?   Same LPAR on z/OS 2.4 does not have 
the same issue.

Thanks,
Ross
