The following software and hardware bugs apply to Sun Fire high-end systems.
Warnings might be displayed when a DR command is executing on a system that is configured with the SunSwift PCI card, Option 1032. These warnings appear on domains that are running either the Solaris 8, Solaris 9, or Solaris 10 software. The following warning is an example:
Aug 12 12:27:41 machine genunix: WARNING: vmem_destroy('pcisch2_dvma'): leaked
These warnings are benign. The Direct Virtual Memory Access (DVMA) space is properly refreshed during the DR operation. No true kernel memory leak occurs.
Workaround: To prevent the warning from being displayed, add the following line to /etc/system:
The link fails between a system with a Sun GigaSwift Ethernet MMF Option X1151A and certain CISCO switches. The failure occurs when you attempt to run a DR operation on such a system that is attached to one of the following switches:
CISCO WS-c4003 switch (f/w: WS-C4003 Software, Version NmpSW: 4.4(1))
CISCO WS-c4003 switch (f/w: WS-C4003 Software, Version NmpSW: 7.1(2))
CISCO WS-c5500 switch (f/w: WS-C5500 Software, Version McpSW: 4.2(1) and NmpSW: 4.2(1))
This problem is not seen on a CISCO 6509 switch.
Workaround: Use another switch. Alternatively, you can consult Cisco for a patch for the listed switches.
