Summary

Novell Cluster Services is a server clustering system that ensures high availability and manageability of critical network resources including data (file systems), applications, and services. It is a multinode clustering product for Linux that is LDAP enabled via Novell eDirectory and supports failover, failback, and migration (load balancing) of individually managed cluster resources.

iSCSI and SLP

Use of iSCSI implies TCP/IP and dual-homed servers. If you properly architect your iSCSI network, you'll have it completely segregated and inaccessible by your client workstations. However, blocking port 524 traffic via ACL, or hiding the network via routing rules is not enough.

NetWare will still present all of its addresses via SLP by default, even if some of them are unreachable. This can cause lengthy delays in service location, drive mappings, etc. To avoid problems with name resolution and login performance, be sure to use the NCP EXCLUDE IP ADDRESS and SLP EXCLUDE IP ADDRESS parameters. Populate them with the IP addresses of the iSCSI network interfaces, to keep clients and other servers on your LAN/WAN from trying to communicate with them on the network you've designated for iSCSI traffic only.
