10 SPARC Enterprise M8000/M9000 Servers Product Notes for XCP 1070 • April 2008
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
There is no workaround.
6592302 Unsuccessful DR operation leaves memory
partially configured.
It might be possible to recover by adding the
board back to the domain with an addboard -
d command.
6614737 The DR deleteboard(8) and moveboard(8)
operations might hang if any of the following
conditions exist:
A DIMM has been degraded.
The domain contains system boards with
different memory size.
Avoid performing DR operations if any of the
following conditions exist:
• Degraded memory – To determine whether the
system contains degraded memory, use the
XSCF command showstatus. For sample
output see “Identifying Degraded Memory in
a System” on page 28.
• Differing memory sizes – To determine whether
the domain contains system boards with
different memory sizes, display the list of
memory sizes using the XSCF command
showdevices or the prtdiag command on
the domain. For sample output, see
“Identifying Different Memory Sizes in a
System Board” on page 28.
If a DR command hangs, reboot the domain to
recover.
6619224 For Solaris domains that include SPARC 64 VII
processors, a single domain of 256 threads or
more might hang for an extended period of
time under certain unusual situations. Upon
recovery, the uptime command will show
extremely high load averages.
For Solaris domains that include SPARC 64 VII
processors, do not exceed a domain size of 256
virtual processors in a single Solaris domain.
This means a maximum of 32 CPUs in a single
domain configuration (maximum configuration
for an M8000 server).
6623226 The Solaris command lockstat(1M) might
cause a system panic.
Do not use the Solaris lockstat(1M)
command.
