Chapter 11 Managing Modules
Upgrading the SSI Boot Image on an SSM
As shown in
Table 11-10
, layer 3 Intelligent Storage Services traffic is disrupted when you update the
SSI boot image. If you have configured layer 3 Intelligent Storage Services on your SSM, we recommend
that you shutdown these services before upgrading the SSI boot image. You can use dual fabric
configuration to minimize the impact of shutting down layer 3 services.
To upgrade or downgrade the SSI boot image Fibre Channel switching and Intelligent Storage Services,
perform the following steps:
Step 1
Verify that the correct SSI boot image is present on your switch (see the
“Verifying the SSI Boot Image”
section on page 11-20
).
Step 2
Update the SSI boot image using one of the following methods:
a.
If your switch is running Cisco MDS SAN-OS Release 2.0(1a) through Release 2.1(1a), configure
the SSI boot variable to upgrade or downgrade the SSI boot image on the module (see the
“Configuring the SSI Image Boot Variable” section on page 11-23
).
b.
Use the
install ssi
command to upgrade or downgrade the SSI boot image on the module (see the
“Using the install ssi Command” section on page 11-25
).
Note
The SSM must be running EPLD version 2.1(2) to use the
install ssi
command. You must
install the SSM on a Cisco MDS 9500 Series switch to upgrade the EPLD. See the
“EPLD
Configuration” section on page 11-12
.
Verifying the SSI Boot Image
To verify that you have the correct Cisco MDS SAN-OS release and SSI boot image file on your switch,
perform the following steps:
Step 1
Log into the switch through the console port, an SSH session, or a Telnet session.
