    Preface This manual describes how to maintain the hardware for PS6000 storage arrays. Each array contains hot-swappable power supply and cooling modules, eight or sixteen RAID-protected disks, and dual hot-swappable control modules. With one or more PS Series arrays, you can create a PS Series group—a self- managing, iSCSI storage area network (SAN) that is affordable and easy to use, regardless of scale.

    2 Maintaining Disks A PS6000 array includes up to 16 hot-swappable disks, either Serial Attached SCSI (SAS) disks or Serial ATA (SATA) disks. Disk maintenance topics apply to both SAS and SATA disks. Removing the Bezel To access the disks in a PS6000, you must remove the bezel. The bezel comes with a lock, which helps protect the disks from being tampered with or accidentally removed.

    PS6000 Hardware Maintenance Maintaining Disks Disk Handling Requirements Handle disks as follows: • Store disks properly. Store replacement disks in the packaging in which they were shipped. Do not stack disks or place anything on top of a disk. • Protect disks from electrostatic discharge.
  • Page 19: Removing Disks

    PS6000 Hardware Maintenance Maintaining Disks For example: • If a spare disk is available, it replaces the failed disk. Performance is normal after reconstruction completes. • If a spare disk is not available and the failed disk is in a RAIDset with no previous disk failure, the RAIDset becomes degraded.

  • Page 23: Maintaining Control Modules

    3 Maintaining Control Modules A PS6000 array includes two hot-swappable control modules. One functioning control module is required for array operation. You access control modules from the rear of the array. Each control module includes multiple Ethernet ports, a serial connector (for use if there is no network access to the array), and a field-replaceable micro SD card (running PS Series firmware).
  • Page 24: Interpreting Control Module Leds

    PS6000 Hardware Maintenance Maintaining Control Modules Interpreting Control Module LEDs Control modules have the following LEDs: • On the left side of each control module, three LEDs enable you to determine the control module status and whether the control module is active or secondary.

  • Page 26: Maintaining Control Module Firmware

    PS6000 Hardware Maintenance Maintaining Control Modules Each control module has four ports: Ethernet 0, Ethernet 1, Ethernet 2, and Ethernet 3. The active control module can use a network interface only if there is a cable connected to the port on the active control module. Therefore, you should connect a cable to the network interface port on each control module to make sure that both control modules can access an interface.

    Instead, contact your array support provider. Network Configuration Recommendations Dell recommends that you follow the guidelines in the table shown next. In addition, all the usual rules for proper network configuration apply to group members.

  • Page 29 PS6000 Hardware Maintenance Maintaining Control Modules • Connect interfaces to different network switches. • At a minimum, connect network cables to Ethernet 0 on both control modules and then connect the cables to a network switch. See Figure 3-2. Figure 3-2: Minimum Network Configuration Although this configuration protects against control module failover, it is still a potential point of failure (for example, if the network cable connected to the active control module is disconnected).

    PS6000 Hardware Maintenance Maintaining Control Modules Figure 3-3: Recommended Network Configuration Control Module Handling Requirements Follow these control module handling requirements: • Protect control modules from electrostatic discharge. Always wear an electrostatic wrist strap when handling a control module, as described in Using an Electrostatic Wrist Strap on page 1-5.
