Follow the onscreen instructions to complete the installation of Device Manager.
Step 4
If you use a Java JDK instead of a JRE on Solaris, you might encounter a problem trying to install the
Note
Device Manager from a web browser. This can happen because the installer heap limit of 256 MB is not
sufficient. If you have this problem, save the jnlp link as file, increase the heap limit to 512 MB, and run
javaws element-manager.jnlp at the shell prompt.
General Upgrading Guidelines
Use the following guidelines when upgrading to Cisco MDS SAN-OS Release 3.3(3):

On an MDS 9222i switch, an upgrade from SAN-OS Release 3.2(x), Release 3.3(1a), or Release 3.3(1c)
Note
to SAN-OS Release 3.3(3) fails when there is an active FC-Redirect configuration (created by Cisco
SME or Cisco DMM applications) on the switch. An active FC-Redirect configuration is defined as:

Install and configure dual supervisor modules.
Issue the show install all impact upgrade-image CLI command to determine if your upgrade will
be nondisruptive.
Follow the recommended guidelines for upgrading a Cisco MDS 9124 Switch as described in
"Upgrading a Cisco MDS 9124 Switch" section on page
Follow the guidelines for upgrading a single supervisor switch as described in
Disruptive Upgrade on a Single Supervisor MDS Family Switch" section on page
Be aware that some features impact whether an upgrade is disruptive or nondisruptive:
Fibre Channel Ports: Traffic on Fibre Channel ports can be nondisruptively upgraded. See
–
Table 6
for the nondisruptive upgrade path for all SAN-OS releases.
SSM: Intelligent services traffic on the SSM, such as SANTap, NASB, and FC write
–
acceleration, is disrupted during an upgrade. SSM Fibre Channel traffic is not.
Gigabit Ethernet Ports: Traffic on Gigabit Ethernet ports is disrupted during an upgrade or
–
downgrade. This includes IPS modules and the Gigabit Ethernet ports on the MPS-14/2 module,
the MSM-18/4 module, and the MDS 9222i switch. Those nodes that are members of VSANs
traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators
connected to the Gigabit Ethernet ports lose connectivity to iSCSI targets while the upgrade is
in progress.
Inter-VSAN Routing (IVR): With IVR enabled, you must follow additional steps if you are
–
upgrading from Cisco SAN-OS Release 2.1.(1a), 2.1(1b), or 2.1.(2a). See the
IVR Enabled" section on page 17
FICON: If you have FICON enabled, the upgrade path is different. See
–

to determine your nondisruptive upgrade path to Cisco SAN-OS Release 3.3(3). Find the
