Known Software and Hardware Bugs
The following software and hardware bugs apply to Sun Fire high-end systems.
Deleteboard Shows Leakage Error (4730142)
Warnings might be displayed when a DR command is executing on a system that is congured
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:
set pcisch:pci_preserve_iommu_tsb=0
GigaSwift Ethernet MMF Link FailsWith CISCO 4003 Switch After DR
Attach
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.
