OK, I've put it in /boot/loader.conf, let's see if it helps. Unfortunately it's a production machine so I cannot reboot it now to try it.

This solves the issue for me on certain embedded systems, and when trying to boot from cheap USB pen drives. I hope this helps.

Slow iSCSI discovery on boot halting the boot process.
Hello,
I'm having an annoying problem with FreeBSD 12.2-RELEASE-p6, iscsid,
geom multiparty, a Dell MD3200i and fstab.
Long story short, iSCSI login/connection/whatever is slower than the
boot process and the machine always get stuck with "cannot find
/san_storage (/dev/multipath/...) please enter /bin/sh location"
Usually we just press enter, press control-d, and the boot process
continues.
The problem is that the machine cannot boot unattended.
Those are some cfg files:
[root@arsenico ~]# cat /etc/fstab
# Device Mountpoint FStype Options Dump Pass#
/dev/mirror/gm0s1a / ufs rw 1 1
/dev/mirror/gm0s1b none swap sw 0 0
md98 none swap sw,file=/usr/swap1,late 0 0
md99 none swap sw,file=/usr/swap0,late 0 0
/dev/mirror/gm0s1d /var ufs rw 2 2
/dev/mirror/gm0s1e /tmp ufs rw 2 2
/dev/mirror/gm0s1f /usr ufs rw 2 2
/dev/mirror/gm0s1g /repository ufs rw 2 2
fdesc /dev/fd fdescfs rw 0 0
/dev/multipath/Krypton /san_storage ufs rw,late 0 0
As you see the filesystem is already flagged as "late"...
[root@arsenico ~]# cat /etc/iscsi.conf
Krypton_C0_P0 {
TargetName=iqn.1984-05.com.dell:powervault.md3200i.6782bcb0007496a24f1e49ee
TargetAddress=10.40.3.200
}
That's the SAN, we dropped the dual connection so maybe we could get rid
of geom_multipath if that is the problem, but... hey...

Any interesting suggestions?
