That's where it should be - /sys/block/<name>/device/delete.

No - that's just a cache reference. As long as the /dev/sd* nodes exist
(and the corresponding /sys/block/sd* entries), the next lvm scan will
pick the devices up and re-add them to the cache.

You could delete the device nodes and/or filter them via lvm.conf, but
since you want them gone (and have masked them from the SAN), you may as
well just delete them.

Bryn.
