HP Cisco MDS 9120 Cisco MDS 9000 Family Release Notes for Cisco MDS SAN-OS Rel - Page 30

Limitations and Restrictions Send documentation comments to [email protected] The Cisco MDS 9222i and the MSM-18/4 do not support Ether channel. The Cisco MDS 9222i supports only the following modules in slot 2: • The Storage Services Module (SSM) • The Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4) • The 8-port Gigabit Ethernet IP Storage services module • The MDS 9000 12-, 24-, and 48-port 4-Gbps Fibre Channel modules • The MDS 9000 4-port 10-Gbps Fibre Channel module The MSM-18/4 and MDS 9222i Switch do not support the following features: • Special frames for FCIP • B ports for San Extension • SAN extension tuner • NetSim • IPv6 • FCIP between the MSM-18/4 and another IPS module Using SAN Device Virtualization on Cisco Fabric Switches There must be at least one SAN device virtualization-enabled switch that is not a Cisco MDS 9124 switch, a Cisco Fabric Switch for HP c-Class BladeSystem, or a Cisco Fabric Switch for IBM BladeCenter between the server and the target that are being virtualized. In other words, SAN device virtualization does not work when initiators and primary targets are connected to the same Cisco MDS 9124 Switch or or Cisco MDS 9134 Switch or Cisco Fabric Switch for HP c-Class BladeSystem or Cisco Fabric Switch for IBM BladeCenter. CWDM SFPs The 2-Gbps CWDM SFPs do not have have a maximum speed set in memory and they negotiate to 4-Gbps on modules that support the higher speed. As a result, the link comes up and appears to work, but then becomes disabled and connectivity problems occur. To correct this problem, both sides of the connection must have their speed hard coded to 2-Gbps. Fabric Manager Observe the following limitations or restrictions for the Cisco SAN-OS Release 3.2(1a) for Fabric Manager: • By default, the database and aaa passwords are stored in plain text. You can encrypt them by using the encrypter.bat/.sh script and pasting the output into the appropriate file, either server.properties or aaa.properties. • The Microsoft Security Patch MS06-040 is known to break applications with a large heap memory. If you increase any Java application's heap (including Fabric Manager) beyond 64 M, we recommend you do not apply this patch. • If port 80 on the switch is blocked and you are using VPN, Fabric Manager cannot detect NAT addresses. The timeout for URL connections is set for 500ms. Cisco MDS 9000 Family Release Notes for Cisco MDS SAN-OS Release 3.2(1a) 30 OL-14116-02
