We should validate zfcp device configuration. Normally we would have multipath enabled too, but as of now storage has only one device, so it should be based on ZFCP_ADAPTERS setting.

We might postpone work on this till we get multipath back and have 2 zfcp devices.
UPDATE: We actually have multipath enabled but for one channel, but we will get 4 devices one we have cables, like we have for old workers: https://openqa.suse.de/tests/4342166#step/disk_activation/12

See #69196 to reuse solution provided there to validate multipath configuration.

See zfcp_disk_configure, chccwdev, lszfcp tools which can be used for validation on top of standard set of tools.

Acceptance criteria¶

1. zfcp disks configuration is validated
2. multipath enablement is validated
3. test data can be easily changed once we have 4 disks
