The picld error messages usually appears after adding or removing the systemboard(s) to/from the system without properly regenerating the i2c sensor devices nodes.

Picld relies on devices nodes located in /devices/pci@9,700000/ebus@1/i2c@1,30 directory to read sensory information from the the system boards.

Examples

An existing Sun Fire V480 system had a new additional system board installed, let's say Board B (CPU1 and CPU3). The system was normally booted without the -r option and the following picld error messages started to appear.

A check on the i2c directory /devices/pci@9,700000/ebus@1/i2c@1,30 only says that the following nodes below are present.

crw-r--r--   1 root     sys      180,  0 Apr 19 01:32 temperature-sensor@0,9c:lm75
crw-------   1 root     sys       10,  0 Apr 19 01:32 temperature@0,30:amb_temp

crw-------   1 root     sys       10, 17 Apr 19 01:32 temperature@0,34:die_temp

Note: It is missing the node entries for CPU1 and CPU3 Die and Ambient temperature sensor nodes. Below are full listing of the i2c sensor nodes for fully populated machine.

A 2xSystemboard (4 CPUs) Sun Fire V480/V490 i2c device nodes

$ cd /devices/pci@9,700000/ebus@1/i2c@1,30
$ ls | grep temperature
...
temperature@0,30:amb_temp <--- CPU0
temperature@0,30:die_temp   <--- CPU0
temperature@0,32:amb_temp <--- CPU1
temperature@0,32:die_temp   <--- CPU1

temperature@0,34:die_temp   <--- CPU2
temperature@0,52:amb_temp <--- CPU3
temperature@0,52:die_temp   <--- CPU3

A 4xSystemboards (8 CPUs) Sun Fire V880/V890 i2c device nodes

$ cd /devices/pci@9,700000/ebus@1/i2c@1,30
$ ls | grep temperature
...
temperature@0,30:amb_temp <--- CPU0
temperature@0,30:die_temp   <--- CPU0

temperature@0,52:amb_temp <--- CPU3
temperature@0,52:die_temp   <--- CPU3
temperature@0,54:amb_temp <--- CPU4
temperature@0,54:die_temp   <--- CPU4
temperature@0,56:amb_temp <--- CPU5
temperature@0,56:die_temp   <--- CPU5
temperature@0,98:amb_temp <--- CPU6
temperature@0,98:die_temp   <--- CPU6
temperature@0,9a:amb_temp <--- CPU7
temperature@0,9a:die_temp   <--- CPU7

If any of the i2c device nodes are missing as defined in the above example, proceed to regenerate the device nodes and restart the picld deamon, you need to be root. This should stop the error messages.

For Example:

root@v4u-480rb # devfsadm -C
root@v4u-480rb # devfsadm
root@v4u-480rb # /etc/init.d/picld stop
root@v4u-480rb # /etc/init.d/picld start

Alternatively the system can be rebooted with the -r option or just plain boot -r from the OK prompt.

For Example:

# reboot -- -r

ok  boot -r
