Configuring a Hot Spare Drive

Configuring a Hot Spare Drive

Scenarios

After hard drives of a server are configured with array properties, hot spare drives are configured to increase security and reduce impact on services caused by hard drive faults.

When the PM8060 is in Legacy or Dual mode, hot spare drives cannot be configured on the management screen.

Prerequisites

Conditions

  • The server has idle hard drives.
  • You have downloaded and installed the arcconf tool on the operating system.

Data

Data preparation is not required for this operation.

Tools

The hot spare drive must be configured by using the official arcconf tool released by the PMC and installed on the operating system.

Procedure

  1. Open the arcconf tool in the operating system.
  2. Run the configuration command for hot spare drives.

    Syntax: arcconf setstate controller ID device channel id device id hsp [logicaldrive LM LN …]

    Parameters in the command are described as follows:

    • controller ID: indicates the controller ID.
    • channel id: indicates the channel ID of the hard drive to be configured. The default value is 0.
    • device id: indicates the slot ID of the hard drive to be configured. (When the hard drive backplane is a pass-through one, the device id is the same as the slot ID of the hard drive. When the hard drive backplane is an expander one, the device id equals the slot ID of the hard drive plus eight.)
    • LM, LN: indicates the designated RAID.

      When logicaldrive is specified, the hot spare drive of a designated RAID is configured. When logicaldrive is not specified, the global hot spare drive is configured.

      The Figure 10-121 shows the process of configuring a hot spare drive.
