Update,
So if I hardcode the LUN to 1, matching my Synology target, then
two(?) targets get attached:
sd1 at scsibus2 targ 0 lun 0: <SYNOLOGY, iSCSI Storage, 4.0>
naa.600140577c3262ed829ed4f8fdb787d2
sd1: 512000MB, 512 bytes/sector, 1048576000 sectors, thin
sd2 at scsibus2 targ 0 lun 1: <SYNOLOGY, iSCSI Storage, 4.0>
naa.600140577c3262ed829ed4f8fdb787d2
sd2: 512000MB, 512 bytes/sector, 1048576000 sectors, thin
I can then access the device and everything seems fine.
Ideas on what could be happening with the initial LUN?
Thanks,
David
