It appears that under some circumstances these two sysfs trees /sys/bus/scsi/drivers/sd/ & /sys/bus/scsi/devices/ may not be populated with the same set of devices.
There are a lot of SCSI devices/LUNs visible on this system from a SAN it was previously connected to. It’s a shame to have to reboot a system just to clear absent block devices so we’re going to have to manually delete them.
Note the -s for the block device path. It seems that some LUNs that were visible on the SAN never had a block device/driver attached to them (or since had it removed). I’ve now decommissioned that old SAN system so I can’t try to reproduce it.

WTH! This had me scratching my head for a while. If you check carefully with the list above you’ll see that the first one liner only removed the LUNs with block devices attached to them.

So lets try that again.

And we’re now completely rid of the old SAN LUNs.
