Replacing a Standby Power Supply

Handling field replaceable units (FRUs)

Handling field replaceable units (FRUs) This section describes the precautions that you must take and the general procedures that you must follow when removing, installing, and storing any field replaceable unit (FRU).

Power issues and FRUs Your storage system is designed to be powered on continuously. Most components are hot swappable; that is, you can replace or install these components while the storage system is running. Front bezels should always be attached and each compartment should contain a FRU or filler panel to ensure EMI compliance and proper air flow over the FRUs. You should not remove a faulty FRU until you have a replacement available. When you replace or install FRUs, you can inadvertently damage the sensitive electronic circuits in the equipment by simply touching them. Electrostatic charge (ESD) that has accumulated on your body discharges through the circuits. If the air in the work area is very dry, running a humidifier in the work area will help decrease the risk of ESD damage. Follow the procedures below to prevent damage to the equipment. Read and understand the following instructions: ◆

Provide enough room to work on the equipment. Clear the work site of any unnecessary materials or materials that naturally build up electrostatic charge,such as foam packaging, foam cups, cellophane wrappers, and similar items.

◆

Do not remove replacement or upgrade FRUs from their antistatic packaging until you are ready to install them.

◆

Before you service a storage system, gather together the ESD kit and all other materials you will need. Once servicing begins, avoid moving away from the work site; otherwise, you may build up an electrostatic charge.

◆

An ESD wristband is supplied with your storage system. To use it, attach the clip of the ESD wristband (strap) to any bare (unpainted) metal on the storage system; then put the wristband around your wrist with the metal button against your skin.

◆

Use the ESD kit when handling any FRU. If an emergency arises and the ESD kit is not available, follow the procedures in the Emergency procedures (without an ESD kit) on page 3.

Emergency procedures (without an ESD kit) In an emergency when an ESD kit is not available, use the procedures below to reduce the possibility of an electrostatic discharge by ensuring that your body and the subassembly are at the same electrostatic potential. These procedures are not a substitute for the use of an ESD kit. Follow them only in the event of an emergency.

◆

Before touching any FRU, touch a bare (unpainted) metal surface of the cabinet or storage system.

◆

Before removing any FRU from its antistatic bag, place one hand firmly on a bare metal surface of the storage system, and at the same time, pick up the FRU while it is still sealed in the antistatic bac. Once you have done this do not move around the room or touch other furnishings, personnel, or surfaces until you have installed the FRU.

◆

When you remove a FRU from the antistatic bag, avoid touching any electronic components and circuits on it.

◆

If you must move around the room or touch other surfaces before installing a FRU, first place the FRU back in the antistatic bag. When you are ready again to install the FRU, repeat these procedures.

Verifying the operation of a new or replacement part

Verifying the operation of a new or replacement part Use Navisphere Express® or Navisphere® Manager to verify the operation of a new or replacement part. If the storage system is running Navisphere Express, use Navisphere Express to verify the operation of a new or replacement part. If the storage system is running Navisphere Manager, use Navisphere Manager to verify the operation of a new or replacement part. Note: All

AX4-5 series storage systems ship with Navisphere Express installed. To use Navisphere Manager, you need to upgrade your storage system to Navisphere Manager.

Verify the operation of a new or replacement part using Navisphere Express 1. In a browser on a network-connected host, start Navisphere® Express for the storage system by entering the IP address of an SP in the storage system. 2. In the Navisphere Express navigation pane, under View , click Components. 3. Scan the list of components to verify that all components are recognized and working properly. If fault lights on storage system are still lit, go to the Celerra Tools page on the http://Powerlink.EMC.com website for more information.

Verifying the operation of a new or replacement part using Navisphere Manager 1. Start Navisphere® Manager for the storage systemby entering the IP address in a browser window. 2. In the Navisphere Manager Storage tree, locate the icon for the storage system in which you installed or replaced the part, expand the storage-system icon, and select the Physical icon. 3. Expand the enclosure in which you installed or replaced the part, and navigate to the part. 4. Verify that the part is in the enclosure and that it is not faulted.

Restoring trespassed virtual disks or LUNs using the CLI

Restoring trespassed virtual disks or LUNs using the CLI When a backend FRU/CRU component fails, the virtual disks or LUNs assigned to that storage processor trespass to the other storage processor. This keeps the data available to the clients. After replacing the failed backend FRU/CRU component you need to restore the virtual disks or LUNs to their original storage processor. 1. Using the CLI, log in to the primary Control Station as nasadmin and change to the root user: su root

2. Determine the storage-system serial number (storage-system ID): nas_storage -list

3. Restore the virtual disks or LUNs to the correct SP: nas_storage –failback storage-system-id

For example: # nas_storage -failback APM00070300923 id = 1 serial_number = APM00070300923 name = APM00070300923 acl = 0 done

This restores the virtual disks or LUNs to the correct SP. After the restore, both SPs have their status listed as OK.

Checking system status

Checking system status Before you begin

You should still be in your HyperTerminal session. Procedure

To view the system state: 1. Enter the following command to verify the system state: # /nas/bin/nas_checkup

Example: # /nas/bin/nas_checkup ]# /nas/bin/nas_checkup Check Version: Check Command: /nas/bin/nas_checkup Check Log : /nas/log/checkup-run.100128-181007.log -------------------------------------Checks------------------------------------Control Station: Checking if file system usage is under limit.............. Pass Control Station: Checking if NAS Storage API is installed correctly........ Pass Control Station: Checking if NBS clients are started.......................
