Solaris OS Issues and Workarounds for All Supported Releases (2 of 4)
TABLE 5
CR ID Description
6535018 In Solaris domains that include SPARC64 VII
processors, workloads that make heavy use of
the Solaris kernel might not scale as expected
when you increase the thread count to a value
greater than 256.
6572827 On Sun SPARC Enterprise M8000/M9000
platforms, one of the columns in the IO
Devices section of the output from prtdiag -
v is "Type". This reports "PCIe", "PCIx", "PCI"
or "UNKN" for each device. The algorithm
used to compute this value is incorrect. It
reports "PCI" for PCI-X leaf devices and
"UNKN" for legacy PCI devices.
6589644 When XSCF switchover happens after the SB
has been added using the addboard
command, the console is no longer available.
6589833 The DR addboard command might cause a
system hang if you are adding a Sun
StorageTek Enterprise Class 4Gb Dual-Port
Fibre Channel PCI-E HBA card (SG-XPCIE2FC-
QF4) at the same time that an SAP process is
attempting to access storage devices attached
to this card. The chance of a system hang is
increased if the following cards are used for
heavy network traffic:
• X4447A-Z, PCI-e Quad-port Gigabit Ethernet
Adapter UTP
• X1027A-Z1, PCI-e Dual 10 Gigabit Ethernet
Fiber XFP Low profile Adapter
6592302 Unsuccessful DR operation leaves memory
partially configured.

Workaround
For Solaris domains that include SPARC64 VII
processors, limit domains to a maximum of 256
threads.
There is no workaround.

There is no workaround.
It might be possible to recover by adding the
board back to the domain with an addboard -
d command.
