I don’t think you can get a guarantee to always have the same ordering. It is much easier to create a custom udev rules.
/etc/udev/rules.d/75-custom.rules:
KERNEL=="sd[b-z][1-9]" BUS=="scsi" SYSFS{serial}=="00000000014defbe2755"
NAME="iscsi1" SYMLINK+="some_name1"
KERNEL=="sd[b-z][1-9]" BUS=="scsi" SYSFS{serial}=="00000000014defbe2756"
NAME="iscsi2" SYMLINK+="some_name2"
KERNEL=="sd[b-z][1-9]" BUS=="scsi" SYSFS{serial}=="00000000014defbe2757"
NAME="iscsi3" SYMLINK+="some_name3"
KERNEL=="sd[b-z][1-9]" BUS=="scsi" SYSFS{serial}=="00000000014defbe2758"
NAME="iscsi4" SYMLINK+="some_name4"And get the SYSFS number from you’re iSCSI disk using the udevinfo command.
udevinfo -a -p $(udevinfo -q path -n /dev/sdd)
udev gives you a lot of flexibility. Give it a try.
