DISPATCH INSTRUCTIONS
WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED: An understanding of Guided Maintenance in R4 and R5

TIME ESTIMATE: 30mins

TASK COMPLEXITY: 0

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS: Log onto the Axiom GUI / Client to access Guided Maintenance

PROBLEM OVERVIEW:

   WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?: The FRU can be Failed/Warning status

   WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE: Read reference docs before proceeding:

Pillar Axiom: How to use Guided Maintenance in R4 and How to identify a FRU

Pillar Axiom: How to use Guided Maintenance in R5 and How to identify a FRU

The capacity of the drive replacement must be equal to or greater than that of the other drives in the Brick enclosure. Access any drive in the storage array from behind the Brick's bezel as shown in the following figure. Drives are numbered from 0 to 11 as shown in the following figure. Drives 0 to 5 are managed by controller 0, while drives 6 to 11 are managed by controller 1.

Do not move drives from their original positions. If you move a drive, all data on that drive will be lost. If multiple drives are moved, you will lose data. If a drive is defective, use Guided Maintenance in the Pillar Axiom Storage Services Manager GUI to replace the drive.

You can also manually replace defective drives without using Guided Maintenance by pulling the bezel with the orange LED light and replacing the drive with the yellow LED light. You may receive some administrative alerts for the disk drive being offline that you can safely ignore Caution: When removing the drives from the Brick, be sure to pull the drive straight out and not turn the drive. The platters may still be spinning and the gyroscope may cause damage. Always use a new Pillar Axiom 600 drive when replacing a drive with or without using Guided Maintenance.

● If a drive fails, do not attempt to recover by removing and reinserting that drive. Contact the Customer Support Center for a new drive.
● If a drive fails, use a sealed spare drive from the Customer Support Center. Do not use a drive of unknown status.
● Do not attempt to replace a failed drive with one from another Brick or from another Pillar Axiom system.
● If a new drive is placed in a Fiber Channel (FC) RAID or Expansion Brick, that new drive should have a green LED indicator and must be in normal state within a few minutes.
● If a new drive is placed in a SATA (version 1) or SATA (version 2) Brick, the drive remains in warning status, until the task to copy back data from the spare drive is complete.
● If testing Drive Pull, wait a few seconds after removing the drive before reinserting it. Be sure to check for Administrator Actions to accept the drive. Important! Contact the Customer Support Center before pulling a drive.
● If a drive fails to be accepted into a Brick and the drive is set to Rejected status, do not attempt to use that drive. Contact the Customer Support Center for another drive and for assistance.
● If an AA is asking you to accept the drive is generated, be sure to select the Accept Drive option, which initiates a copyback operation. If an Administrator Action (AA) to Accept a Drive is ever answered negatively, do not attempt to use that drive again. Contact Support for another drive.

SATA Non-Spare Drive Replacement

1. Within Guided Maintenance, click Next in the Prepare System page.
2. When Guided Maintenance prompts you to remove the drive, press the cam latch button on the face of the drive carrier to release the cam latch.
3. Open the cam latch fully.
    Result: The drive disengages from the Brick's midplane. The system then begins rebuilding the data that was on the drive from parity data to the spare drive. This process can take several hours.
4. Slide the drive out of the chassis and set it aside.

Note: You can manually replace defective drives without using Guided Maintenance. Always use a new Pillar Axiom 600drive when replacing a drive.
Caution Immediately replace the component to maintain proper airflow and cooling. Over-temperature conditions will occur if the replacement FRU is not installed into the chassis. Over-temperature conditions can damage other components.
Only factory-fresh, Pillar-supplied drives are supported in Pillar Axiom systems. These drives have a unique identifier. The process of writing this identifier to the physical drive is called branding. If the drive is unbranded, the Pillar Axiom system rejects it. Important! The capacity of the drive replacement must be equal to or greater than that of the other drives in the Brick enclosure. After Guided Maintenance successfully validates the drive replacement, the drive is bound to the Brick in which it was added. Any and all data that existed on the drive will be erased.

If you observe an Administrator Action to accept the foreign drive, be sure to click Accept. If the drive came from a spares kit, the Accept Foreign Drive task should begin automatically within a few minutes.

Note: If a Copyback or Rebuild operation to this drive occurs, the Accept Foreign Drive task will not complete until that operation completes. After you insert this FRU into a Brick control unit (CU), use Guided Maintenance to complete the replacement procedure.

Important! If Guided Maintenance encounters a problem at this stage, you must contact the Pillar World Wide Customer Support Center to continue Guided Maintenance for this FRU.
When the FRU replacement process is complete, the Pillar Axiom system reports the status of the FRU.

Insert a Drive

Inserting a drive improperly can cause errors and faults. Follow these instructions to ensure success.

1. Fully open the cam latch on the replacement drive and slide the drive into the Brick chassis until it snaps into place.
    If a drive is not fully seated, either or both of the following will be true:
    ● The metal portion of the carrier will be visible.
    ● The front of the drive carrier will not be flush with the other carriers. Important! Do not unlatch and re-latch a drive carrier unnecessarily. Doing so can lead to potential troubles in the future.

2. Close the cam latch until it snaps shut to engage the drive with the Brick midplane.
    Result: The center LED should flash green for up to one minute.

3. In Guided Maintenance, click Next.

While the system checks the drive for acceptance, the drive status displays as Foreign. Also, you should see brief bursts of activity on the top and bottom LEDs as each RAID controller checks the drive. After a short while, the center LED should light steady green. Important! If the center LED    lights amber, the system has rejected the drive or the drive failed to spin up properly. Contact the Customer Support Center.

4. Choose one of the following options:
    ● If prompted to acknowledge the successful discovery of the drive replacement, click OK to accept the drive.
    ● If the replacement is not new, Guided Maintenance displays a dialog box that contains the prompt “Are you sure you want to do this?”
       Choose one:
    ○ Click OK to accept the replacement.
    Acceptance binds this drive to this Brick and destroys any data that may have existed on the drive.

Note: When you click OK, the system copies the data from the spare drive back to the array drive. The status of this drive is Copying Back and the spare drive remains in use during this period. Under some circumstances, if there are two failed drives in the Brick, the new drive may go to a Rebuild status indicating that the array is being rebuilt from parity.
    ○ Click Cancel to reject the replacement. Rejection terminates this procedure and retains any previous data that might have existed on the drive. Important! If you reject the drive, you cannot use it in this system again.

5. When the copyback process completes, review the status of the replacement FRU to ensure that:
    ● The status of the replacement FRU is Normal.
    ● The task to accept the drive has completed successfully.

OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE: Complete guided maintenance

PARTS NOTE:

Return the parts if requested by Support/Engineering via the CPAS system. Otherwise dispose of replaced parts as normal
