Configuring iSLB Chapter 50 Configuring iSCSI Send documentation comments to [email protected] Note Only statically mapped iSLB initiator configuration is distributed throughout the fabric using CFS. Dynamically and statically mapped iSCSI initiator configurations are not distributed. • Dynamic load balancing of iSLB initiators is available using iSCSI login redirect and VRRP. This section covers the following topics: • About iSLB Configuration Limits, page 50-36 • iSLB Configuration Prerequisites, page 50-37 • About iSLB Initiators, page 50-37 • Configuring iSLB using Device Manager, page 50-37 • Configuring iSLB Initiators, page 50-39 • About Load Balancing Using VRRP, page 50-43 • Configuring Load Balancing Using VRRP, page 50-45 • About iSLB Configuration Distribution Using CFS, page 50-46 • Distributing the iSLB Configuration Using CFS, page 50-47 Note Before configuring iSLB, you must enable iSCSI (see the "Enabling iSCSI" section on page 50-4). Note For iSLB, all switches in the fabric must be running Cisco MDS SAN-OS Release 2.1(1a) or later. About iSLB Configuration Limits iSLB configuration has the following limits: • The maximum number of iSLB and iSCSI initiators supported in a fabric is 2000. • The maximum number of iSLB and iSCSI sessions supported by an IPS port in either transparent or proxy initiator mode is 500. • The maximum number of iSLBinitiators supported in a fabric is 2000. • The maximum number of iSLB sessions per IPS port in either transparent or proxy initiator mode is 500. • The maximum number of switches in a fabric that can have iSLB with CFS distribution enabled is four. • No more than 200 new iSLB initiators can be added to the pending configuration. Before adding more initiators, you must commit the configuration. • You cannot disable iSCSI if you have more than 200 iSLB initiators in the running configuration. Reduce the number of iSLB initiators to fewer than 200 before disabling iSCSI. • iSLB can be used without CFS distribution but if iSLB auto-zone feature is used, traffic is disrupted when any zoneset is activated. 50-36 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x

Cisco MDS 9000 Family CLI Configuration Guide

OL-16184-01, Cisco MDS SAN-OS Release 3.x

Chapter 50

Configuring iSCSI

Configuring iSLB

Note

Only statically mapped iSLB initiator configuration is distributed throughout the fabric

using CFS. Dynamically and statically mapped iSCSI initiator configurations are not

distributed.

•

Dynamic load balancing of iSLB initiators is available using iSCSI login redirect and VRRP.

This section covers the following topics:

•

About iSLB Configuration Limits, page 50-36

•

iSLB Configuration Prerequisites, page 50-37

•

About iSLB Initiators, page 50-37

•

Configuring Load Balancing Using VRRP, page 50-45

•

About iSLB Configuration Distribution Using CFS, page 50-46

•

Distributing the iSLB Configuration Using CFS, page 50-47

Note

Before configuring iSLB, you must enable iSCSI (see the

“Enabling iSCSI” section on page 50-4

Note

For iSLB, all switches in the fabric must be running Cisco MDS SAN-OS Release 2.1(1a) or later.

About iSLB Configuration Limits

iSLB configuration has the following limits:

•

The maximum number of iSLB and iSCSI initiators supported in a fabric is 2000.

•

The maximum number of iSLB and iSCSI sessions supported by an IPS port in either transparent or

proxy initiator mode is 500.

•

The maximum number of iSLBinitiators supported in a fabric is 2000.

•

The maximum number of iSLB sessions per IPS port in either transparent or proxy initiator mode is

500.

•

The maximum number of switches in a fabric that can have iSLB with CFS distribution enabled is

four.

•

No more than 200 new iSLB initiators can be added to the pending configuration. Before adding

more initiators, you must commit the configuration.

•

You cannot disable iSCSI if you have more than 200 iSLB initiators in the running configuration.

Reduce the number of iSLB initiators to fewer than 200 before disabling iSCSI.

•

iSLB can be used without CFS distribution but if iSLB auto-zone feature is used, traffic is disrupted

when any zoneset is activated.
