fcrlsanmatrix --fabricview
The following is an example:
FCR:Admin > fcrlsanmatrix --fabricview
LSAN MATRIX is activated
Fabric ID 1 Fabric ID 2
--------------------------------------
4 5
4 7
10 19
Default LSAN Matrix:
1 2 8
See the Fabric OS Command Reference Manual for additional information on the
fcrlsanmatrix
command.
Dual backbone configuration
When dual backbones share edge fabrics, one of the backbone is selected to be the owner of the edge
fabric which sends device state updates to the other backbone through the shared edge fabric. With the
‘LSAN Zone binding’ feature is enabled, the LSAN Zone Matrix settings for the shared edge fabrics must
be the same on both backbones. Both backbone fabrics must have the same LSAN Zone Matrix settings.
If the settings are different, the outcome will be inconsistent. Both backbone fabrics will end up having the
setup of the owner fabric which can change on reboot or portdisable/enable.
Maximum LSAN count
The
fcrlsancount
command lets you configure the maximum number of LSANs, or LSAN count, that
can be configured on the edge fabric, which is up to 5000 without disabling the switch. By default, the
maximum LSAN count is set to 3000. This command lets you create more LSANs on your edge fabric
where needed. The maximum devices supported is still 10000. This command is also supported in Secure
Fabric OS.
The
fcrlsancount
command assumes that all the FCRs in the same LSAN fabric matrix or backbone
have the same maximum number of LSAN count defined, to protect all the FCRs from running into indefinite
state. Asymmetric LSAN configurations due to different maximum LSAN counts could lead to different
devices being imported on different FCRs.
The following example shows the use of the
fcrlsancount
command that allows you to display the
current LSAN limit or to set the maximum LSAN Zone count:
To display the current LSAN limit
switch:admin> fcrlsancount
LSAN Zone Limit 3000
To set the new LSAN zone limit
switch:admin> fcrlsancount 5000
LSAN Zone Limit 5000
For information on how to display the new maximum LSAN count after it has been changed, see
Monitoring resources , page 256.
Since the maximum number of LSANs is configured per switch, if there is a different maximum LSAN count
on the switches throughout the metaSAN, then the device import/export will not be identical on the FCRs.
You should 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.
