Hardware Restrictions

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

• Multihost tape, CD-ROM, and DVD-ROM are not supported.

• 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 StorEdge^TM A3500, for which two paths are supported to each of two nodes.

  • Devices using Sun StorEdge Traffic Manager.

  • EMC storage devices that use EMC PowerPath software.

  • Sun StorEdge 9900 storage devices that use HDLM.

• If you are using a Sun Enterprise^TM 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 VTS^TM software is not supported.
