Description

After some recent changes in the zfcp connectivity, validate_multipath module is failing.

The main reason of the failure is that after the changes, we have two wwid entries instead of one.
Compare the listed wwids (output at the bottom) from this job to this one.
This results in the stored $wwid output in the validate_multipath module to contain two lines with two different worldwide identifiers.

Similarly, due to this, the output of multipath -ll now contains two device mapper devices instead of one.
This can be seen here in contrast to this old job.

This setup results in two commands being susceptible to failure.

  1. The first is assert_matches(qr/$wwid dm-0 $ven_pro_rev/, $topology_output, 'General topology info are not displayed properly');. This of course fails because $wwid contains two lines of identifiers corresponding to the two multipath maps. This is the failure seen in our zfcp jobs currently.
  2. The second one is validate_script_output("multipath -d -v3 | grep ^$wwid", qr/$wwid.*$name/);. If the previous command would not exist the jobs would fail here because, once more, the $wwid parameter no longer contains only one WWID, and also because it is related to a different disk.

Observation

openQA test in scenario sle-15-SP4-Online-s390x-zfcp@s390x-zfcp fails in
validate_multipath

Test suite description

Testsuite maintained at https://gitlab.suse.de/qa-maintenance/qam-openqa-yml. Maintainer: QE Yast, mgriessmeier

Installation-only test configuring an s390x ZFCP storage.

Reproducible

Fails since (at least) Build 29.1

Expected result

Last good: (unknown) (or more recent)

Further details

Always latest result in this scenario: latest

Suggestion

A good middle ground solution would be to store in the $wwid parameter only one of the identifiers matching to a single multipath map.
This would mean that both commands 1. and 2. listed on the top of the description would pass.
This is not a compromise, since we will still test the validity of one multipath map (as was the case for 15-SP3, before this change had occured)
