Access the controller via a telnet client; log into the controller over the network (default user name manage and password !manage). If the default user or password — or both — have been changed for security reasons, enter the secure login credentials instead of the defaults shown above.

    Procedures This chapter provides procedures for replacing FRUs (field-replaceable units), including precautions, removal instructions, installation instructions, and verification of successful installation. Each procedure addresses a specific task. Certain procedures refer to related documentation. See Related documentation on page 9 for a list of these documents and where to find them online. Electrostatic discharge Before you begin any of the procedures, consider the following precautions and preventive measures.

  • Page 28: Replacing Chassis Fru Components

    Replacing chassis FRU components Chassis FRUs replace a damaged chassis or chassis components. A fully functional chassis requires successful installation of the following components: • One or two controller modules of the same model (for a given controller enclosure) Replacing a controller module or expansion module on page 29 for more information.

  • Page 29: Replacing A Controller Module Or Expansion Module

    Replacing a controller module or expansion module IMPORTANT: The replacement controller is pre-loaded with TS200 or later firmware. This requires that a second controller — in a dual-controller configuration — be upgraded to the same code version in order to operate properly.

  • Page 30: Configuring Partner Firmware Update

    CAUTION: When replacing a controller module, ensure that less than 10 seconds elapse between inserting it into a slot and fully latching it in place. Failing to do so might cause the controller to fail. If it is not latched within 10 seconds, remove the controller module from the slot, and repeat the process. Configuring partner firmware update In a dual-controller system in which Partner Firmware Update (PFU) is enabled, when you update firmware on one controller, the system automatically updates the partner controller.

  • Page 31: Stopping I/O

    Stopping I/O When troubleshooting drive and connectivity faults, ensure you have a current full backup. As an additional data protection precaution, stop all I/O to the affected vdisks. IMPORTANT: Stopping I/O to a vdisk is a host-side task, and falls outside the scope of this document. When on-site, you can verify that there is no I/O activity by briefly monitoring the system LEDs;...

  • Page 36: Replacing A Disk Drive Module

    You can update firmware using RAIDar or using FTP (File Transfer Protocol). See the AssuredSAN 3000 Series RAIDar User Guide for more information. Replacing a disk drive module A disk drive module consists of a disk in a sled. Disk drive modules are hot-swappable, which means they can be replaced without halting I/O to the vdisks, or powering off the enclosure.

    Using the CLI: 6. Log in to the CLI (use default user manage and password !manage, or the appropriate username and password if they have been changed). 7. To view information about disks, run the following command: show disks <disk-ID> Disks are specified by enclosure ID and slot number.

  • Page 41: Before You Begin

    When replacing a power supply FRU, you might accidentally disconnect cables, causing disks to go offline. As a precaution — before installing or replacing a FRU — you should stop I/O to all vdisks. If stopping I/O is not possible, the next best action is to defer FRU replacement until such time as it is possible to stop all I/O.

  • Page 42: Power Supply Units

    Power supply units IMPORTANT: Newer AC power supply units do not have power switches. These PSUs power on when connected to a power source, and power off when disconnected. Power cycling procedures vary according to the type of power supply included within the enclosure. For controller and expansion enclosures configured with AC PSUs that do not have power switches, refer to the procedure described under AC PSU...

    To install a power supply module, perform the following steps: 1. Orient the PSU with the AC or DC connector toward the right as shown in Figure 26 on page 44 and Figure 27 on page 44, respectively. 2. With the latch in the open position, slide the module into the appropriate power supply slot as far as it will go.

    a. Connect a DC power cable to each DC power supply using the D-shell connector. Use the UP> arrow on the connector shell to ensure proper positioning (see adjacent left side view of D-shell connector). b. Tighten the screws at the top and bottom of the shell, applying a torque between 1.7 N-m (15 in-lb) and 2.3 N-m (20 in-lb), to securely attach the cable to the DC PSU.
