    The Sun StorEdge T3 disk tray expansion unit contains the same components as the Sun StorEdge T3 disk tray controller unit except for the internal RAID controller.

  • Page 29: Disk Tray Features

    Disk Tray Features The Sun StorEdge T3 disk tray provides high reliability while being simple to administer and maintain. It features a design that supports high availability, high performance, configuration flexibility, and scalability of bandwidth, capacity, and input/output operations per second (IOPS). These key features are summarized in the following table depicting a disk tray with nine 18-Gbyte drives.

  • Page 30: Components

    Components The Sun StorEdge T3 disk tray contains four basic components that can be easily replaced: Disk drive Controller card Interconnect card Power and cooling unit All components plug into a centerplane; there is no internal cabling. For information on how to remove and replace these components see the service procedures in Chapter 5.

  • Page 45: Installing The Disk Tray

    Note – In some cases, it is possible that the disk tray could time out before it receives the RARP request through an Ethernet switch. If this happens, the disk tray cannot receive the assigned IP address. If the disk tray should time out before receiving the RARP request, it could be due to an improper spanning-tree setting of the Ethernet switch.

  • Page 46: Cabinet Installation

    Caution – Use two people to lift the disk tray to avoid injury. It can weigh up to 67 pounds (30 kg). 1. Place the Sun StorEdge T3 disk tray horizontally in the designated location. Caution – Do not place the disk tray in a vertical position.

  • Page 47: Figure 2-3 Removing The Feet

    Note – Retrieve the placement information for the disk tray before beginning the installation. Caution – This procedure requires two people to lift and move the disk tray. Use care to avoid injury. A disk tray with a baseplate attached can weigh up to 87 pounds (39 kg).

  • Page 78: Changing The Default Configuration

    2.11 Changing the Default Configuration The default configuration for the Sun StorEdge T3 disk tray is a RAID 5 volume. If you want to change the default configuration, do so now before continuing the installation process. Configuration options for the disk tray are discussed in Chapter 3.

  • Page 79: Verifying The Data Host Connection

    Note – If you are creating new volumes or changing the volume configuration, you must first manually rewrite the label of the previous volume using the autoconfigure option of the format(1M) utility. Refer to the Sun StorEdge T3 Disk Tray Administrator’s Guide for more information on this procedure.

  • Page 80: Creating Soft Partitions On The Data Host

    Note – There are two commands available to determine the drive volume capacity of the Sun StorEdge T3 disk tray. Within the disk tray, the vol command is used to display the raw volume capacity. Within the Solaris environment, the format(1M) utility (among others) can be used to display the capacity of a newly created volume.

  • Page 81: Establishing Alternate Pathing On The Host

    Note – This completes the installation process for a single disk tray installation. If you are configuring a partner group, you must continue to the next section. 2.12.4 Establishing Alternate Pathing on the Host This task applies only when two controller units are configured as a partner group. In a partner group, controller caches are mirrored so that if one controller fails, no data is lost.

  • Page 87: Reconfiguring The Disk Tray Settings

    Reconfiguring the Disk Tray Settings The disk tray has been set with the following default configuration: RAID 5 volume; no hot spare Cache mode set to auto Autodisable and autoreconstruction of disk drives These default settings and other possible configurations are described in the following sections.

  • Page 88: Raid Levels

    The RAID level determines how the controller reads and writes data and parity on the drives. The Sun StorEdge T3 disk tray can be configured with RAID level 0, RAID level 1 (1+0), or RAID level 5. The default configuration is a RAID level 5.
  • Page 89 3.2.2.1 RAID 0 Data blocks in a RAID 0 volume are striped across all the drives in the volume in order. There is no parity data, so RAID 0 uses the full capacity of the drives. There is no redundancy, however; if a single drive fails, all data on the volume is lost. shows the data layout in a RAID 0 volume.

  • Page 90: Cache Modes

    Four cache modes are supported: auto, write-behind, write-through, and none. The default mode for the Sun StorEdge T3 disk tray is set to auto. In the auto cache mode, if the disk tray has full redundancy available, then the caching mode is write-behind.
  • Page 91 The write-through cache mode forces write-through caching to always be used. Read caching is also performed in this mode. The none cache mode forces no write caching and no read caching. Caution – If there is a failure of one of the redundant components, the cache mode is set to write-through.

    Troubleshooting This chapter describes how to approach troubleshooting the Sun StorEdge T3 disk tray. Use the information in this chapter along with the Sun StorEdge T3 Disk Tray Administrator’s Guide or Sun StorEdge Component Manager User’s Guide to determine the service required. This chapter is organized as follows: “Analyzing the Problem”...

    To see details of problems internal to the Sun StorEdge T3 disk tray, use the tool(s) that you installed on your management console. In a partner-group configuration where alternate pathing failover has been established, the failure of a channel path or disk tray controller causes the host to redirect I/O from the failed channel to the second FC-AL connection.
