Chapter 6 Configuring SCSI Routing
Configuring Access to iSCSI Targets
You can also associate up to two access lists with an iSCSI target: one allowing read/write access, and
one allowing read-only access. The default access is read/write. Access lists are evaluated read/write
first, and then read-only, so if an IP host is associated with both types of lists, it will be allowed
read/write access.
Note Some host operating systems impose restrictions on the use of read-only access lists. For details, see the
readme files and release notes for your IP host operating system.
Use the procedures that follow according to the type of access:
• Configuring access to one iSCSI target at a time
• Configuring access to all iSCSI targets at once
• Denying access to one or more iSCSI targets
• Configuring read/write and read-only access
Configuring access to one iSCSI target at a time
This section provides two procedures: one for configuring access to an iSCSI target by specific IP hosts,
and one for configuring access to an iSCSI target by any iSCSI host.
Use the following procedure to configure access to one iSCSI target on a per-IP host basis by associating
the iSCSI target with a named access list.
Use the following procedure to configure access to one iSCSI target by any iSCSI host.
Configuring access to all iSCSI targets at once
This section provides two procedures: one for configuring access to all iSCSI targets by specific IP hosts,
and one for configuring access to all iSCSI targets by any IP host.
Use the following procedure to configure access to all iSCSI targets associated with a SCSI routing
instance. Access is controlled on a per-IP host basis by associating the iSCSI targets with a named access
list.
Command Description
Step 1
enable Enter Administrator mode.
Step 2
scsirouter zeus target
chimaera_apps accesslist aegis
Specify that an iSCSI target (chimaera_apps), configured as part
of a SCSI routing instance (zeus), can only be accessed by IP hosts
listed in an access list (aegis). Because access is read/write by
default, it does not need to be specified.
Command Description
Step 1
enable Enter Administrator mode.
Step 2
scsirouter zeus target
pegasus_email accesslist any
Specify that an iSCSI target (pegasus_email), configured as part of
a SCSI routing instance (zeus), can be accessed by any IP host.
Because access is read/write by default, it does not need to be
specified.
