64-bit SPARC: DR Operations Involving Lowest CPU ID
Fail (6663570)
Dynamic reconguration (DR) operations involving the lowest CPU ID might cause the
domain to panic. The following error message is displayed:
panic[cpu40]/thread=2a1008ebca0: BAD TRAP: type=10 rp=xxxxxxx addr=xxxxxxx mmu_fsr=0
Workaround: Do not use DR to identify the system board hosting the CPU with the lowest
CPU ID. Use the prtdiag command to identify the CPU with the lowest CPU ID.
SPARC: 19.55% Performance Regression for the NCP
Device Driver (6660074)
Performance regression occurs for the Niagara Crypto Provider (NCP) device driver on Sun
SPARC® Enterprise T5220 machines with the Solaris 10 5/08 release. No error message is
displayed.
Workaround: Add the following line to the /platform/sun4v/kernel/drv/ncp.conf
conguration le:
ncp-threads-per-core=6;
64-bit SPARC: Some DR Commands Fail (6614737)
The DR commands, deleteboard(8) and moveboard(8), might hang if any of the following
conditions exist:
■
A dual in-line memory module (DIMM) has been degraded.
■
The domain contains system boards with dierent memory sizes.
No error message is displayed.
Workaround: If a DR command hangs, reboot the domain to recover.
Avoid performing DR operations if any of the listed conditions exist.
To identify if the system contains degraded memory, use the XSCF showstatus command. To
identify if the domain contains system boards with dierent memory sizes, use the XSCF
showdevices command. You can also use the prtdiag command on the domain to display the
list of memory sizes of the system boards.
