ldc_skt and ds Might Not Handle LDC Resets Properly (CR

6583567)

Very rarely, a communication channel between the primary domain and the service

processor (SP) could hang and disable communication over the channel.

Workarounds:

If the channel is one that is used by a primary domain service or application other

than the Fault Management daemon (fmd), for example the LDoms Manager ldmd,

you could see warning or error messages concerning communication failures. In this

case, the channel can be brought back up by restarting the affected service or

application.

If the channel is the one used by fmd, there are no warning or error messages. fmd

will not receive reports and diagnosis of the errors does not occur.

If a domain crashes or a service spontaneously restarts without any associated fault

messages, you must recover as follows to minimize potential loss of error telemetry.

1. Restart fmd on the primary domain.

2. Wait 30 seconds.

3. Reset the SP with either of the following commands:

4. Restart fmd on the primary domain.

Enter the following command from the Solaris OS:

If the channel is the one used by the operating system (Solaris) to communicate with

the SP, you could see warning or error messages regarding failure to obtain the PRI;

failure to access ASR data; or failure to set LDoms variables or failure in SNMP

communication. In this case, the channel can be brought back up by resetting the SP.

If the SP is reset, restart the fmd on the primary domain. If resetting the SP fails to

bring the channel back up, then it might also be necessary to reboot the primary

domain.
