Limitations and Restrictions Send documentation comments to [email protected] Deleting Cisco SME Interfaces A Cisco SME interface can be deleted from the cluster only after the interface is administratively shut-down and all related tasks associated with the interface shut-down are complete. Emulex Driver Version In some instances, the Emulex driver version 8.1.10.9 may set the task attribute to HEAD_OF_QUEUE instead of SIMPLE_QUEUE. Certain tape drives do not accept this attribute and may reject these commands. The Emulex driver version 8.1.10.12 does not have this issue. Cisco MDS 9222i Module Upgrade On the MDS 9222i module, an upgrade from SAN-OS Release 3.2(x) to Release 3.3(1c) is not supported if there is a Cisco SME or Cisco DMM configuration in the fabric for hosts and targets attached to the MDS 9222i module. SANTap The SANTap feature allows third party data storage applications, such as long distance replication and continuous backup, to be integrated into the SAN. SANTap is not supported in Release 3.3(4). Deleting SANTap Configurations Is Required Before Downgrade If you are running Cisco MDS NX-OS Release 4.1(1b) in combination with the SSI 4.1(1b) image and you wish to downgrade to Cisco SAN-OS Release 3.3(4) and an SSI 3.2(3*) image, you must delete all SANTap configurations prior to the downgrade. Downgrading without completely deleting the SANTap configurations is not supported. FCIP Interoperability FCIP interoperability fails between two MDS switches, one running MDS NX-OS Release 4.1(1c) and the other running MDS SAN-OS Release 3.3(4), if the IP ACL configuration for an IPSec crypto map specifies TCP as the protocol, as in the following example: switch(config)# ip access-list acl-name permit tcp local-gige-ip-address local-mask remote-gige-ipaddress remote-mask FCIP interoperability does not fail if the IP ACL uses IP as the protocol, as in the following example: switch(config)# ip access-list acl-name permit ip local-gige-ip-address local-mask remote-gige-ipaddress remote-mask Applying Zone Configurations to VSAN 1 In the setup script, you can configure system default values for the default-zone to be permit or deny, and you can configure default values for the zone distribution method and for the zone mode.
