MAAS ID_PATH is empty for FC storage array

[jarred wilson]

I am using debian package maas/focal 1:2.9.2-9164-g.ac176b5c4-0ubuntu1~20.04.1 all

I am attempting to configure some nodes in MAAS. fce uses the bdev ID_PATHS to correlate the generated buckets and pci address and the configured buckets. for these fiber channel storage arrays provided via UCS, the ID_PATH of a maas root node-results read system_id=agsdfg name=fce_blockdevs for example is an empty list as shown here:

 }
]

Looking at /dev/disk/by-id/ we can see several devices here:

The original post is incorrect, this is with MAAS maas/focal 1:3.0.0-10029-g.986ea3e45-0ubuntu1~20.04.1 all
