Maintaining a StorEdge T3/T3+ Disk Tray

This section contains the procedures for maintaining a StorEdge T3 or StorEdge T3+ disk tray. The following table lists these procedures. This section does not include a procedure for adding a disk drive and a procedure for removing a disk drive because a StorEdge T3/T3+ disk tray only operates when fully configured.

Caution - Caution -

If you remove any field-replaceable unit (FRU) for an extended period of time, thermal complications might result. To prevent this complication, the StorEdge T3/T3+ disk tray is designed so an orderly shutdown occurs when you remove a component for longer than 30 minutes. A replacement part must be immediately available before starting a FRU replacement procedure. You must replace a FRU within 30 minutes or the StorEdge T3/T3+ disk tray, and all attached StorEdge T3/T3+ disk trays, will shut down and power off.

How to Upgrade StorEdge T3/T3+ Disk Tray Firmware

Use this procedure to upgrade StorEdge T3/T3+ disk tray firmware in a running cluster. StorEdge T3/T3+ disk tray firmware includes controller firmware, unit interconnect card (UIC) firmware, and disk drive firmware.

Caution - Caution -

Perform this procedure on one StorEdge T3/T3+ disk tray at a time. This procedure requires that you reset the StorEdge T3/T3+ disk tray you are upgrading. If you reset more than one StorEdge T3/T3+ disk tray, your cluster will lose access to data if the StorEdge T3/T3+ disk trays are submirrors of each other.

  1. On one node attached to the StorEdge T3/T3+ disk tray you are upgrading, detach that StorEdge T3/T3+ disk tray's submirrors.

    For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

  2. Apply the controller, disk drive, and UIC firmware patches.

    See the Sun Cluster 3.0 U1 Release Notes for information about accessing Sun's EarlyNotifier web pages, which list information about any required patches or firmware levels that are available for download. For the procedure on applying any host adapter firmware patch, see the firmware patch README file.

  3. Reset the StorEdge T3/T3+ disk tray, if you have not already done so.

    For the procedure on rebooting a StorEdge T3/T3+ disk tray, see the Sun StorEdge T3 Installation, Operation, and Service Manual.

  4. Reattach the submirrors to resynchronize them.

    For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

How to Replace a Disk Drive

Use this procedure to replace one failed disk drive in a StorEdge T3/T3+ disk tray in a running cluster.

Caution - Caution -

If you remove any field replaceable unit (FRU) for an extended period of time, thermal complications might result. To prevent this complication, the StorEdge T3/T3+ disk tray is designed so an orderly shutdown occurs when you remove a component for longer than 30 minutes. A replacement part must be immediately available before starting a FRU replacement procedure. You must replace a FRU within 30 minutes or the StorEdge T3/T3+ disk tray, and all attached StorEdge T3/T3+ disk trays, will shut down and power off.

  1. If the failed disk drive impacted the logical volume's availability, remove the logical volume from volume management control. Otherwise, proceed to Step 2.

    For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

  2. Replace the disk drive.

    For the procedure on replacing a disk drive, see the Sun StorEdge T3 Installation, Operation, and Service Manual.

  3. If you removed a LUN from volume management control in Step 1, return the LUN(s) to volume management control. Otherwise, Step 2 completes this procedure.

    For more information, see your Solstice DiskSuite or VERITAS Volume Manager documentation.

How to Add a StorEdge T3/T3+ Disk Tray

Use this procedure to add a new StorEdge T3/T3+ disk tray to a running cluster.

This procedure defines Node A as the node you begin working with, and Node B as the remaining node.

  1. Set up a Reverse Address Resolution Protocol (RARP) server on the network the new StorEdge T3/T3+ disk tray is to reside on, and then assign an IP address to the new StorEdge T3/T3+ disk tray.

    This RARP server enables you to assign an IP address to the new StorEdge T3/T3+ disk tray by using the StorEdge T3/T3+ disk tray's unique MAC address.

    For the procedure on setting up a RARP server, see the Sun StorEdge T3 Installation, Operation, and Service Manual.

  2. (Skip this step if you are adding a StorEdge T3+ disk tray) Install the media interface adapter (MIA) in the StorEdge T3 disk tray you are adding as shown in Figure C-2.

    For the procedure on installing a media interface adapter (MIA), see the Sun StorEdge T3 Configuration Guide.

  3. If necessary, install a gigabit interface converter (GBIC) in the Sun StorEdge FC-100 hub as shown in Figure C-2.

    This GBIC enables you to connect the Sun StorEdge FC-100 hub to the StorEdge T3/T3+ disk tray you are adding.

    For the procedure on installing an FC-100 hub GBIC, see the FC-100 Hub Installation and Service Manual.

  4. Install the Ethernet cable between the StorEdge T3/T3+ disk tray and the Local Area Network (LAN), as shown in Figure C-2.

  5. Power on the StorEdge T3/T3+ disk tray.

    Note -

    The StorEdge T3/T3+ disk tray might require a few minutes to boot.

    For the procedure on powering on a StorEdge T3/T3+ disk tray, see the Sun StorEdge T3 Installation, Operation, and Service Manual.

  6. Telnet to the StorEdge T3/T3+ disk tray you are adding, and, if necessary, install the required StorEdge T3/T3+ disk tray controller firmware.

    See the Sun Cluster 3.0 U1 Release Notes for information about accessing Sun's EarlyNotifier web pages, which list information about any required patches or firmware levels that are available for download. For the procedure on applying any host adapter firmware patch, see the firmware patch README file.

  7. Does this new StorEdge T3/T3+ disk tray have a unique target address?

    • If yes, proceed to Step 8.

    • If no, change the target address for this new StorEdge T3/T3+ disk tray.

    For the procedure on verifying and assigning a target address, see the Sun StorEdge T3 Configuration Guide.

  8. Install a fiber-optic cable between the Sun StorEdge FC-100 hub and the StorEdge T3/T3+ disk tray as shown in Figure C-2.

    For the procedure on installing a fiber-optic cable, see the Sun StorEdge T3 Configuration Guide.

    Figure C-2 Adding a StorEdge T3/T3+ Disk Tray in a Single-Controller Configuration

    Graphic

    Note -

    Although Figure C-2 shows a single-controller configuration, two disk trays are shown to illustrate how two non-interconnected disk trays are typically cabled in a cluster to allow data sharing and host-based mirroring.
