Option 1: Attaching additional J-Class with unconfigured hard disk drives currently installed.

  1. Be sure the new J-Class system is powered off.
  2. Temporarily unlatch all disks installed in the JClass chassis.
  3. Connect the SAS cables from the JClass chassis to the currently powered on and running E-Class or last J-Class in the chain. The connection go from Circle on the last device in the running enclosures to the Diamond input SAS connection on the new J-Class chassis.
  4. Power on the newly installed J-Class chassis.
  5. Once the new J-Class is up and running, verify that the E-Class can see the newly attached chassis by checking in WebPam or CLI. If the chassis is not detected, please contact Promise Technical Support for assistance.
  6. If the enclosure is seen, now it is safe to hot plug the unconfigured drives into the JClass chassis.
  7. Once all disks are detected, you will be able to create arrays and logical drives as needed.

Option 2: Removing a running J-Class with an arrays already configured and moving from one subsystem to another.

  1. Before shutting down and detaching the running J-Class, log into WebPAM or CLI and put the array into a 'Transit' state.
  2. Once the array is in Transit state, unlatch the disks from the chassis to be removed. Note this chassis must be the last chassis in the SAS cable chain.
  3. After unlatching the drives, power off the VTrak and detach the SAS cables.

At this point the JClass can be removed and/or moved to another E-Class or E/J-Class combination

  1. Connect the SAS cables from the JClass chassis to the currently powered on and running E-Class or last J-Class in the chain. The connection go from Circle on the last device in the running enclosures to the Diamond input SAS connection on the new J-Class chassis.
  2. Power on the newly installed J-Class chassis.
  3. Once the additional J-Class is up and running, verify that the E-Class can see the newly attached chassis by checking in WebPam or CLI. If the chassis is not detected, please contact Promise Technical Support for assistance.
  4. If the enclosure is seen, now it is safe to hot plug the drives that are in Transit mode into the JClass chassis.
  5. Once all drives are installed, the array will come out of Transit mode and be put online so the array and logical drives can be seen.
