HP Cisco MDS 9120 Cisco MDS 9000 Family Release Notes for Cisco MDS SAN-OS Rel - Page 36

Caveats Send documentation comments to [email protected] Symptom: If there are IP over Fibre Channel (IPFC) interfaces configured on an SSM, you might experience issues if you downgrade from SAN-OS Release 3.x to Release 2.x. Workaround: Before downgrading, remove the IPFC interface on the module and then recreate the IPFC interface after the downgrade is complete. • CSCse47687 Symptom: If IP ACLs are applied to any IP Storage Gigabit Ethernet port, implicit deny does not take effect. Workaround: Configure explicit deny on the port. • CSCsg19148 Symptom: Time zone changes that are executed on an MDS switch do not take effect on the 12-port, 24-port, and 48 port 1-Gbps/2-Gbps/4-Gbps Fibre Channel modules, and on the 4-port 10-Gbps module. This issue occurs in SAN-OS Releases 3.0(1), 3.0(2), 3.0(2a), and 3.0(3). Time zone changes that are executed on an MDS switch do not take effect on the 16-port or 32-port 1-Gbps/2-Gbps module, on the 4-port or 8-port Gigabit Ethernet IP services module, the MPS 14/2 module, and on the SSM. This issue occurs in SAN-OS Release 3.0(3). This issue has no effect on functionality. However, debug messages and syslogs from the MDS switching modules have incorrect timestamps if the time zone is configured on an MDS switch. Workaround: None. • CSCsg19303 Symptom: Graceful shutdowns of ISLs are not supported for IVR traffic. Workaround: Increase the fspf cost on the link before it is shut down, so that traffic will flow through an alternate path. • CSCsi66310 Symptom: The management port on MDS switches supports one user-configured IPv6 address, but does not support autoconfiguration of an IPv6 address in Cisco SAN-OS Release 3.2(1). Workaround: None. • CSCsj24904 Symptom: On a Gigabit Ethernet interface on the MDS MSM-18/4, shut the interface before removing its IP address so that configuration changes on the interface can take effect. This applies only to the Gigabit Ethernet ports in slot 1 of the MDS 9222i Switch and the MDS 9216i Switch. Workaround: Always shut the interface using the shutdown command before removing the IP address and making configuration changes. • CSCsk00953 Symptom: HP Blade Servers that are connected through an HP Virtual Connect (VC) FC module to a Cisco Fabric Switch for HP c-Class BladeSystem using NPIV lose access to LUNs when load balancing on the VC module is switched from 16:1 to 8:1. When the load balancing ratio is 16:1, all servers connect through interface ext1. When the ratio is 8:1, servers 1 and 3 connect through ext1, servers 2 and 4 connect through ext2, and so on. Servers on ext2 are not affected by the switchover. In addition, packets might get dropped when the switchover occurs. Workaround: None. • CSCsk18352 Symptom: If a supervisor switchover occurs while Fabric Manager is creating a DMM job, the job creation process times out.
