1.6.2 For PRIMECLUSTER

When using PRIMECLUSTER, you need to set the SCF/RCI monitoring timeout according to partition configuration of RCI connecting units.

Notes

• You can calculate the timeout using the largest number of partitions in an RCI connecting unit.
• Enable the timeout by rebooting the node.

For GP7000F model 200/200R/400/400A/400R/600/600, and PRIMEPOWER200/400/600

The monitoring timeout setting is not required.

For PRIMEPOWER 250/450

The monitoring timeout setting is not required.

For GP7000F model 1000/2000, and PRIMEPOWER 800/1000/2000

Set up the monitoring timeout in the /etc/system file as follows:

• Calculating monitoring timeout
  • 1 or 2 nodes: 2 seconds
  • 3 or more partitions: 1 second + (0.5 x number of partitions)
    • Example 1) 3 partitions: 2.5 seconds
    • Example 2) 4 partitions: 3.0 seconds

• Setting up the /etc/system file

Change the /etc/system file on all cluster nodes, as follows:

1. Copy (or backup) /etc/system using /etc/system.org:

     Example: # cp /etc/system /etc/system.org

2. Add the following to /etc/system. As the timeout is set up in *s units, set a value equal to the value calculated above, multiplied by 1000000:

set FJSVscf2:scf_rdctrl_sense_wait = (monitoring timeout: *s unit)
For example, /etc/system is specified for 2-partition configuration as follows:
set FJSVscf2:scf_rdctrl_sense_wait = 2000000

3. Reboot the system

For PRIMEPOWER 650/850

The monitoring timeout setting is not required.

For PRIMEPOWER 900/1500/2500/HPC2500

Set up the monitoring timeout in the /etc/system file as follows:

• Calculating monitoring timeout
  • 1 or 2 partitions : 2 seconds
  • 3 or more partitions: 1 second + (0.5 x number of partitions)
    • Example 1) 3 partitions: 2.5 seconds
    • Example 2) 4 partitions: 3.0 seconds

• Setting up the /etc/system file

Change the /etc/system file on all the nodes, as follows:

1. Copy (or backup) /etc/system using /etc/system.org:

    Example: # cp /etc/system /etc/system.org

2. Add the following to /etc/system. As the timeout is set up in *s units, set a value equal to the value calculated above, multiplied by 1000000:

set FJSVscf3:scf_rdctrl_sense_wait = (monitoring timeout: *s unit)
For example, /etc/system is specified for 2-partition configuration as follows:
set FJSVscf3:scf_rdctrl_sense_wait = 2000000

3. Reboot the system
