Replacing a Service Disk Module

Replacing a Service Disk Module

This section explains how to replace a service disk module for a P12.

Impact on the System

During the interval between removing a service disk module and installing the replacement service disk module, system performance is compromised. Therefore, replace a service disk module during off-peak hours.

Prerequisites

  • The service data on the faulty service disk module has been backed up.
  • The replacement service disk module is ready. The type of the replacement disk and faulty disk are same. The capacity of the replacement disk module is equal to or larger than that of the faulty disk module.
  • The faulty service disk module has been located. Figure 2-1 shows the service disk module slot number.

Precaution

  • To prevent damaging service disk modules or connectors, remove or install service disk modules with even force.
  • When you remove a service disk module, first remove it from the port. Wait at least 30 seconds and remove the service disk module completely from the chassis.
  • To prevent service disk module from damage, wait at least 1 minute after removal and before reinserting a service disk module, or after insertion and before removal of a service disk module.
  • To prevent data loss, replace the located faulty disk only and do not remove or insert other disks unless necessary.
  • To prevent system failure, do not change a used hard drive into the node.
  • Restricted by the storage principles, SSDs and mechanical disks such as NL-SAS, SAS and SATA disks cannot be preserved for a long term while they are powered off.
    • SSDs where no data is stored can be preserved for a maximum of 12 months while they are powered off. SSDs where data has been stored can be preserved for a maximum of 3 months while they are powered off. If the maximum preservation time is exceeded, data loss or SSD failure may occur.
    • Packed mechanical disks can be preserved for a maximum of six months. Unpacked mechanical disks that are powered off can be preserved for a maximum of six months too. If the maximum preservation time is exceeded, data loss or disk failure may occur.
    • The maximum preservation time is determined based on the disk preservation specifications provided by the mechanical disk vendor. For details about the specifications, see the manual provided by the vendor.
  • Do not use disks of which the sector format is 4Kn (that is, the sector size is 4 KB) for parts replacement. For disks that can be used by OceanStor 9000, 2.5-inch disks with 1.2 TB or larger capacity and 3.5-inch disks with 6 TB or larger capacity are disks of which the sector format is 4Kn. If you must use disks with the 4Kn sector format, upgrade the system to V100R001C30SPC200 or later, and then perform parts replacement.
  • You can replace a faulty large-capacity SSD with a small-capacity SSD only in slot 0. In other conditions, do not replace a faulty large-capacity disk with a small-capacity disk of the same type. Otherwise, the system will prevent the disk from running.

Tools and Materials

  • ESD gloves
  • ESD wrist strap
  • ESD bag
  • Labels

Procedure

  1. Wear the ESD wrist strap and ESD gloves. For details, see Put on an ESD wrist strap in Replacing a Main Control Board Enclosure.
  2. Press the latch on the handle to eject the handle of the service disk module, as shown in step 1 in Figure 2-2.
  3. Open the handle, as shown in step 2 in Figure 2-2.
  4. Wait at least 30 seconds and slowly remove the service disk module from the chassis, as shown in step 3 in Figure 2-2.

  5. Put the removed service disk module into an ESD bag.
  6. Take the replacement service disk module out of its ESD bag.
  7. Insert the service disk module into the empty slot, as shown in step 1 in Figure 2-3.

    NOTE:

    Before inserting a service disk module, stretch the handle of the service disk module to the maximum angle. Otherwise, the service disk module may fail to be fully inserted into the slot.

  8. Close the handle, as shown in step 2 in Figure 2-3.

  9. After inserting a service disk module, wait 3 minutes, and then check the disk module alarm/location indicator to determine whether the service disk module has been successfully installed.

    • If the disk module running indicator is steady on or blinking green, and the disk module alarm/location indicator is off, the installation is successful.
    • The possible causes of a red-on disk module alarm/location indicator are:
      • The service disk module is not firmly inserted. Remove and reinsert the service disk module. Refer to 2 to 4 to remove the service disk module. Wait 1 minute and install the service disk module again.
      • If the disk module alarm/location indicator is still steady red after you have reinserted the service disk module, the replacement service disk module may be faulty. Replace the service disk module with another one.
      • If the disk module alarm/location indicator is still steady red after the replacement, the link of the service disk module slot may be broken. In that case, contact the technical support engineers.

  10. Check and upgrade disk firmware.
    1. Log in to the CLI. For details, see Logging In to the CLI in OceanStor 9000 Command Reference.
    2. Run show disk general to check whether the firmware of the replaced disk needs to be upgraded. If any record shows that the value of DiskNeedUpg is YES, the firmware needs to be upgraded.

      • If yes, record nodeID and location in the command output where the value of DiskNeedUpg is YES.
      • If no, the disk firmware does not need to be upgraded.

    3. Log in to DeviceManager. At the lower right of the home page, click Task Management and check whether any data reconstruction tasks are incomplete.

      • If yes, check the data reconstruction progress and wait until the data reconstruction tasks are complete.
      • If no, go to 10.d.

    4. On the CLI, run upgrade disk node_id slot_id to upgrade the disk firmware.

      node_id and slot_id are the values of nodeID and location recorded in 10.b. The upgrade takes approximately 3 minutes. Once the upgrade is complete, a data reconstruction task is generated automatically. If you are going to upgrade other disks, wait until this data reconstruction task is complete.

    5. Repeat 10.a to 10.d to upgrade all disk firmware that needs to be upgraded.

Follow-up Procedure

After the service disk module is replaced, label the replaced service disk module to facilitate subsequent operations.
