That depends on what storage subsystem(s) you are using. There is no general solution to that. Starting points would be the "fget_config" command for FC-disks, the "maymap" command for SSA-disks. For SCSI-disks the task should be obvious.
I hope this helps.

tgt-setup-lun
tgt-setup-lun(8) System Manager's Manual tgt-setup-lun(8)
NAME
tgt-setup-lun - creates a target, adds a device to the target and defines initiators that can connect to the target
SYNOPSIS
tgt-setup-lun -d device -n target_name [initiator_IP1 initiator_IP2 ...] [-h]
DESCRIPTION
Starts tgtd if necessary and creates a target according to the supplied target_name. The format of the target name is as follows:
iqn.2001-04.com.<hostname>-<target_name> The target name must be unique.
The script then adds the requested device to the target. If specific IP addresses are defined, it adds them to the list of allowed initia-
tors for that target. If no IP addresses is defined, it defines that the target accepts any initiator.
EXAMPLES
Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81:
tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81
Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81 and 192.168.10.82:
tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 192.168.10.82
Create a target that uses /dev/sdb1 and allows connections from any initiator:
tgt-setup-lun -d /dev/sdb1 -n my_target
Display help:
tgt-setup-lun -h
