group tag.
<port number> is the port number
associated with the portal group tag.
It is optional and if not specified the
well-known iSCSI port number of
3260 is used.
<timeout> is optional, it applies to
all the portals in the group.
The timeout value is in milliseconds
and needs to be multiple of 100ms.
It is used to detect loss of
communications at the iSCSI level.
NOTE: There can be multiple target
IP address/port numbers per portal
group tag. This enables a target to
operate on multiple interfaces for
instance.
<portalgrouptagX>The portalgroup
to which login requests should be
redirected to.
NOTE: There can be multiple
redirection target portalgroups
specified for a particular target portal
group and the redirection will
happen to these in a round robin
manner.
No To turn ShadowMode on or off for
iSCSI Target Redirection
No The maximum number of
outstanding iSCSI commands per
session.
No A device served up by the
associated target.
The device mode can be a:
•
Block Device (e.g., /dev/sda)
•
Virtual Block Device (e.g.,
/dev/md0)
•
RamDisk
•
Regular File
<path/name> is the path to the
device - with the exception of when
a RAM Disk is specified, where it is
a unique name given to the device.
If multiple RAM Disks are used for a
target then each name must be
unique within the target.
NULLRW specifies that random
data is returned for reads, and for
writes data is dropped. Useful for
testing network performance.
