The following restrictions apply to hardware in all Sun Cluster configurations.

Alternate pathing (AP) is not supported.
Storage devices with more than a single path from a given cluster node to the enclosure are not supported except for the following storage devices:
Sun StorEdgeTM A3500, for which two paths are supported to each of two nodes.

If you are using a Sun EnterpriseTM 420R server with a PCI card in slot J4701, the motherboard must be at dash-level 15 or higher (501–5168–15 or higher). To find the motherboard part number and revision level, look at the edge of the board closest to PCI slot 1.
System panics have been observed in clusters when UDWIS I/O cards are used in slot 0 of a board in a Sun Enterprise 10000 server; do not install UDWIS I/O cards in slot 0 of this server.
Sun VTSTM software is not supported.
