Fabric OS Command Reference 345

53-1003131-01

fcrLsanCount

Displays or sets the maximum LSAN count.

SYNOPSIS fcrlsancount [max_lsan_count]

DESCRIPTION Use this command to set or display the maximum number of LSAN zones that can be configured on the

edge fabric. By default, the maximum LSAN count is set to 3000, which is also the minimum. This

command allows you to create up to 5000 LSANs on your edge fabric, if needed to support additional

devices. The maximum number of supported LSAN devices is 10,000.

When executed without operand, this command displays the current LSAN zone limit.

This command assumes that all FCRs in the same LSAN fabric matrix or backbone have the same

maximum LSAN count defined in order to protect the FCRs from running into indefinite state. Asymmetric

LSAN configurations due to different maximum LSAN counts may lead to different devices being

imported on different FCRs.

Because the maximum number of LSANs is configured per switch, if there is a different maximum LSAN

count on the switches throughout the meta-SAN, the device import or export will not be identical on the

FCRs. You should therefore enter the same maximum LSAN count for all the FCR switches in the same

backbone that support this feature. Verify the configured maximum limit against the LSANs configured

using the fcrResourceShow command.

NOTES The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in

place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for

details.

OPERANDS This command has the following operands:

max_lsan_count

Specifies the maximum LSAN count.

EXAMPLES To display the current LSAN limit:

switch:admin> fcrlsancount

LSAN Zone Limit: 3000

To increase the LSAN zone limit:

switch:admin> fcrlsancount 5000

LSAN Zone Limit: 5000
