Minor Faults Reported by SC Causes N1 Provisioning Server to Classify Blades as Failed/Unusable (4998378)

During installation when pestest is run or during runtime when farm activation is taking place, you might see the following message on your screen or in the debug log:

device-id: test FAILED: Reason was:  - Cannot save state information for device-id: Blade Sn seems to be faulty

Workaround: To prevent problems with later farm activation, you must do one of the following:

• Replace the defective blade. This blade is defective and needs to be replaced as soon as possible. Follow these steps:

  1. Type the following command to see the properties of the blade that is referred to by device-id in the message:

     # /opt/terraspring/sbin/device -l device-id

  2. Examine the FARM_ID column.

     If the FARM_ID column does not contain a hyphen (-), the blade is part of a farm.

     If the blade is part of a farm, type the following command to replace the failed blade in the farm with another blade that has similar attributes:

     # /opt/terraspring/sbin/replacedevice farm-id failed-device-id

  3. To find the ID of the shelf that houses this blade, type the following command:

     # /opt/terraspring/sbin/device -l device-id

     Look for a line similar to the following:

     cpu:sun-b100s-blade (- -) 50100:s0 ==> pwr:sun-b1600-pwr (- -) 50160:s0

     In this example, the device ID for the shelf is 50160.

  4. To determine the IP address for the shelf, type the following command:

     # /opt/terraspring/sbin/device -lv shelf-device-id

     Look for the field ipaddress: to obtain the IP address of the shelf.

  5. Telnet to the shelf and type the following command to inform the shelf controller that the blade is to be prepared for removal:

     # replacefru Sn

     In response to this command, a blue LED will light on the blade.

  6. Approach the blade shelf front panel and remove the defective blade.

     The defective blade will have a blue LED that differentiates the defective blade from other blades in the shelf.

  7. Insert a good blade into the blade shelf to replace the defective blade.

  8. To detect the new blade and update the information in the database, type the following command:

     # /opt/terraspring/sbin/shelfsync

  9. To retest the blades, type the following command:

     # /opt/terraspring/sbin/pestest

• Mark the blade as FAILED. If you choose not to replace the defective blade, you must mark that blade as FAILED. Otherwise, your farm activation could fail if the defective blade is used in the farm. Follow these steps:

  1. Type the following command to see the properties of the blade:

     # /opt/terraspring/sbin/device -l device-id

  2. Examine the FARM_ID column.

     If the FARM_ID column does not contain a hyphen (-), the blade is part of a farm.

     Type the following command to replace the failed blade in the farm with another blade that has similar attributes:

     # /opt/terraspring/sbin/replacedevice farm-id failed-device-id

  3. Examine the STATE column.

     If the STATE is not set to FAILED, type the following command to set the state to FAILED:

     # /opt/terraspring/sbin/device -sB device-id
