  2. Once the processor is shutdown, remove and replace a system board or any replacable part on the system board by following the procedures described in Chapater 11 of the SPARCcenter 2000 System Service Manual.

  3. After a part or system board has been replaced, power the processor on as indicated in Chapter 7, "Shutdown and Restart Procedures";.

9.2.2 SPARCstorage Array

9.2.2.1 Trays and Disk Drives

  1. Shut disk tray down as described in Chapter 7, "Shutdown and Restart Procedures";.

  2. To gain access to the disk trays in a SPARCstorage array, first remove the lower vented panel from the cabinet front.

    a. Grasp the panel under the vent on one side and pull out far enough to just disengage the ball studs.

    b. Repeat this procedure on the other side of the vents to disengage and remove the panel. Set the panel aside.

  3. Remove the two right-hand mounting screws securing the boot disk bracket to the chassis and then swing the bracket out and to the left.

    See Figure 9-6.

CAUTION Caution - Use care when removing disk trays from a SPARCstorage array, so that the two boot disks and cabling are not damaged.
  1. Remove and replace defective drive as described in Chapter 5 of the

    SPARCstorage Array Model 100 Series Service Manual.

  2. Swing the disk mounting bracket closed and then secure the bracket to the chassis using the two screws removed in step 3.

9.2.3 Boot Disks

Two boot disks are mounted in the lower front of each SPARCcluster 2000HA cabinet directly behind the lower vented panel. The disks are mounted together in a single enclosure (Multi-Disk Pack) that is in turn mounted in a hinged bracket that swings out for access. The Multi-Disk Pack is secured to the hinged bracket with a holding plate.
Both boot disks and the associated processor should be powered off during replacement of a single disk. The data on the disk that is to be replaced should be backed up prior to powering off the disk. To replace a boot disk:
  1. Power down the boot disks as described in Chapter 7, "Shutdown and Restart Procedures";.

  2. Remove the lower vented panel from the cabinet front.

    a. Grasp the panel under the vent on one side and pull out far enough to just disengage the ball studs.

    b. Repeat this procedure on the other side of the vents to disengage and remove the panel. Set the panel aside.

  3. Remove the two right-hand mounting screws securing the boot disk bracket to the chassis and then swing the bracket out and to the left as shown in Figure 9-6.

图形

  1. Use the power switch located on the back panel of the boot disk enclosure to power off both disks and then remove the SCSI cable connecting the Multi-Disk Pack to the computer system.

CAUTION Caution - Once the nuts are removed as described in the following step, the enclosure holding both disks will be free of the bracket. Use caution when replacing either disk.
  1. Remove three nuts from each side of the holding plate as shown in Figure 9-6, and then remove the Multi-Disk Pack.

  2. Replace the desired disk.

    Refer to the Multi-Disk Pack Installation and Service Guide for the disk replacement procedure as well as the procedure for determining the present SCSI target ID for the disk. Refer to Appendix C for the SCSI addresses for the boot disks and reset the disk address if necessary.

  3. Secure the Multi-Disk Pack to the bracket using the six nuts removed in step 5.

  4. Replace the SCSI cable to the Multi-Disk Pack and then power on both units using the power switch on the rear of the Multi-Disk Pack.
