Drive Replacement

・ Isilon NL400 Replace a drive |
・ Isilon_H500-Isilon Gen6 3.5inch Drive Replacement.pdf |

  1. Confirm the node number and bay number of the drive you want to remove:

    OneFS 8.0 or later isi_for_array -s isi devices drive list | grep -v HEALTHY
    Earlier than OneFS 8.0 isi_for_array -s isi devices | grep -v HEALTHY

  2. Using the node number and bay number of the drive, smartfail the drive by typing one of the following commands:

    OneFS 8.0 or later isi devices drive smartfail <bay-number> --node-lnn <node-number>
    Earlier than OneFS 8.0 isi devices -a smartfail -d <node-number>:bay<bay-number>

    CAUTION: Do not replace the drive until you have confirmed that the smartfail process is complete, and drive state is [REPLACE].

  3. Connect the drive to the node using the node number and bay number where you just inserted the drive:

    OneFS 8.1 or later OneFS will automatically add the drive. If ARR (Automatic Replacement Recognition) has been disabled, add the drive with the OneFS 8.0 command.
    OneFS 8.0 isi devices drive add <bay-number> --node-lnn <node-number>
    Earlier than OneFS 8.0 isi devices -a add -d <node-number>:<bay-number>

    The add command connects the drive to the node.

  4. If the add command fails, make sure that the drive is formatted by running one of the following commands:

    OneFS 8.0 or later isi devices format <bay-number> --node-lnn <node-number>
    Earlier than OneFS 8.0 isi devices -a format -d <node-number>:<bay-number>

Drive State

State Description Method Error state
HEALTHY All drives in the node are functioning correctly. Command-line interface, web administration interface
SMARTFAIL or Smartfail or restripe in progress The drive is in the process of being removed safely from the file system, either because of an I/O error or by user request. Nodes or drives in a smartfail or read-only state affect only write quorum. Command-line interface, web administration interface
NOT AVAILABLE A drive is unavailable for a variety of reasons. You can click the bay to view detailed information about this condition.
Note: In the web administration interface, this state includes the ERASE and SED_ERROR command-line interface states.		 Command-line interface, web administration interface X
SUSPENDED This state indicates that drive activity is temporarily suspended and the drive is not in use. The state is manually initiated and does not occur during normal cluster activity. Command-line interface, web administration interface
NOT IN USE A node in an offline state affects both read and write quorum. Command-line interface, web administration interface
REPLACE The drive was smartfailed successfully and is ready to be replaced. Command-line interface only
STALLED The drive is stalled and undergoing stall evaluation. Stall evaluation is the process of checking drives that are slow or having other issues. Depending on the outcome of the evaluation, the drive may return to service or be smartfailed. This is a transient state. Command-line interface only
NEW The drive is new and blank. This is the state that a drive is in when you run the isi dev command with the -a add option. Command-line interface only
USED The drive was added and contained an Isilon GUID but the drive is not from this node. This drive likely will be formatted into the cluster. Command-line interface only
PREPARING The drive is undergoing a format operation. The drive state changes to HEALTHY when the format is successful. Command-line interface only
EMPTY No drive is in this bay. Command-line interface only
WRONG_TYPE The drive type is wrong for this node. For example, a non-SED drive in a SED node, SAS instead of the expected SATA drive type. Command-line interface only
BOOT_DRIVE Unique to the A100 drive, which has boot drives in its bays. Command-line interface only
SED_ERROR The drive cannot be acknowledged by the OneFS system.
Note: In the web administration interface, this state is included in Not available.		 Command-line interface, web administration interface X
ERASE The drive is ready for removal but needs your attention because the data has not been erased. You can erase the drive manually to guarantee that data is removed.
Note: In the web administration interface, this state is included in Not available.		 Command-line interface only
INSECURE Data on the self-encrypted drive is accessible by unauthorized personnel. Self-encrypting drives should never be used for non-encrypted data purposes.
Note: In the web administration interface, this state is labeled Unencrypted SED.		 Command-line interface only X
UNENCRYPTED SED Data on the self-encrypted drive is accessible by unauthorized personnel. Self-encrypting drives should never be used for non-encrypted data purposes.
Note: In the command-line interface, this state is labeled INSECURE.		 Web administration interface only X
