Problems That Might Occur in Any Versions of Oracle Solaris and Workarounds


Problems That Might Occur in Any Versions of Oracle Solaris and Workarounds
The following table lists the problems that might occur in any versions of Oracle Solaris being supported and workarounds for them.
Table 3-48  Problems That Might Occur in Any Versions of Oracle Solaris and Workarounds
Bug 24718083
Model SPARC M12-1, SPARC M12-2, SPARC M12-2S, SPARC M10-1, SPARC M10-4, SPARC M10-4S
Description If the XSCF is rebooted while the control domain is running, the power capping function will not work.
Workaround There is no effective workaround.
[How to restore]
Execute the svcadm command to restart the ldoms/ldmd service.
# svcadm restart ldmd
Bug 23025823
Model SPARC M12-2S, SPARC M10-4S
Description The addboard command fails to revert the I/O devices which have been degraded with the deleteboard command.
This phenomenon occurs when all of the following conditions are true:
- There is/are root domain(s) with two or more root complexes.

- The deleteboard command removes root complexes from the root domain(s).

- At least one endpoint in one or more of the removed root complexes is either unassigned or assigned to another domain.

- The addboard command restores the root complex(es).

Moreover, once this phenomenon occurs, retrying addboard fails and the ldmd daemon might dump core.
Workaround Execute the addboard command with -m bind=none option and recover the I/O configuration manually.

Model SPARC M12-1, SPARC M12-2, SPARC M12-2S, SPARC M10-1, SPARC M10-4, SPARC M10-4S
Description When a logical domain with a 10 Gigabit Ethernet card (SP1X7HF1F) for which the value of the OpenBoot PROM environment variable diag-switch? is set to true, the console displays the following warning message and the error log records "Msg: Device error (FCode informed error)".
WARNING: /pci@X,XXXXXX: FCODE mapin doesn't match decoded register type;

Also, executing the showstatus(8) command may show "Degraded" for the FRU on which the relevant PCI card is mounted.
Workaround Ignore all these outputs.
To prevent these outputs, execute the following command on the ok prompt to change the value of the OpenBoot PROM environment variable diag-switch? to false.
setenv diag-switch? false

Model SPARC M12-2S, SPARC M10-4S
Description If dynamic reconfiguration is performed on a physical partition which has a dual channel 10G FCoE card (SP1X7FBR2F/SP1X7FBS2F/7101683 (7101684)+7101687 (7101688)) mounted on it, system panic may occur due to the processing of the emlxs driver.
Workaround There is no effective workaround.
Use Oracle Solaris 11.2 SRU 11.2.2.8.0 or later and Oracle Solaris 10 1/13 or later.
If this specific card is mounted on a system, conduct any reconfiguration in deactivated state instead of dynamic reconfiguration.
Bug -
Model SPARC M12-2S, SPARC M10-4S
Description If dynamic reconfiguration is performed on a physical partition which has a Dual Port Gigabit Ethernet card (MMF) (SP1X7GD1F/7100482 (7100481)), connection is terminated.
Workaround There is no effective workaround.
If this specific card is mounted on a system, conduct any reconfiguration in deactivated state instead of dynamic reconfiguration.

Model SPARC M12-1, SPARC M12-2, SPARC M12-2S, SPARC M10-1, SPARC M10-4, SPARC M10-4S
Description When "Oracle VM Server for SPARC 3.1.1.1" is installed on the control domain, messages like the following will be registered to the log file (/var/svc/log/ldoms-ldmd:default.log) of the ldoms/ldmd service.
[Example of message]
Get Device ID command failed: Unknown (0x7E)
ERROR: Cannot connect to BMC
Workaround There is no effective workaround.
Ignore this message because there is no impact on system operation.

Model SPARC M12-2S, SPARC M10-4S
Description When physical partition dynamic reconfiguration (PPAR DR) is performed to replace a building block in a physical partition containing logical domains with the whole-core constraint and logical domains without the whole-core constraint, the number of CPUs and memory size of the whole-core constrained domains may not be restored correctly.
With the ldm list-domain command, you can check whether the whole-core constraint is enabled for a logical domain. In the following example, the whole-core constraint is applied on the logical domain domain-A and not on the logical domain domain-B.
primary# ldm list-domain -o resmgmt
NAME
domain-A

CONSTRAINT
    cpu=whole-core
    max-cores=unlimited

--------------------------------------------------------------------

NAME
domain-B
 
CONSTRAINT
Workaround Enable the whole-core constraint for all logical domains in the physical partition, or disable it for all the logical domains.
For details on how to set the whole-core constraint, see the Oracle VM Server for SPARC 3.4 Administration Guide.
[How to restore]
Execute the ldm command to manually restore the resources of the domain.

Model SPARC M12-1, SPARC M12-2, SPARC M12-2S
Description When you start the SunVTS 7.0 ps19 tests on a SPARC M12 system, they may terminate with an error.
Workaround There is no effective workaround.
