Replacing a boot drive

You can replace a failed boot drive in the field.

This node contains two flash boot drives. The boot drives contain data vital to the health

of the node, including the OneFS operating system and backups of the node journal. The

two boot drives mirror each other, which provides a backup source of data if one of the

drives fails.

You must identify which of the two boot drives has failed before you shut down the node.

If you accidentally remove the healthy drive, the data on the node can be lost.

Clusters running in SmartLock compliance mode require a sudo prefix to run root

commands.

If a cluster is running in SmartLock compliance mode, root access is disabled on the

cluster. Because of this, you can run some commands only through the sudo program.

Prefixing a command with sudo enables you to run commands that require root access.

For example, if you do not have root access, the following command fails:

However, if you are on the sudoers list, the following command succeeds:

Before you begin any maintenance on a cluster, gather cluster logs.

You must collect cluster logs before all maintenance procedures. Cluster logs provide

snapshots of the cluster, which you can review to make sure that maintenance is

successful.

Procedure

1. Open a secure shell (SSH) connection to any node in the cluster and log in.

2. Gather cluster logs by running the following command:

Procedure

1. Go to the EMC Support page that lists all the available versions of the drive support

package.

2. Click the latest version of the drive support package and download the file.

See the Considerations for installing the latest drive support package section in order

to select the appropriate variant of the package. If you are unable to download the

package, contact EMC Isilon Technical Support for assistance.

3. Open a secure shell (SSH) connection to any node in the cluster and log in.

7. Install the package by running the following command:

You must run the isi_dsp_install command to install the dirve support package.

Do not use the isi pkg command.

Download a Field Replacement Unit (FRU) package

Before you replace a component in a configure-to-order (CTO) node, obtain a Field

Replacement Unit (FRU) package from the EMC FTP site. The FRU package updates the

CTO and as-built information on the node, then forwards the updated information to

IsiFru_Package_

3. Place the FRU package on the cluster through a network drop, or by asking someone

at the cluster site to place the package for you. If neither of these options is available

to you, contact Isilon Technical Support for assistance.

Install the boot drive replacement

Identify and remove the failed boot drive, and then install and test the replacement drive.

Because replacement of an incorrect boot drive severely affects cluster stability, verify the

successful replacement of the failed drive. Prior to replacing the failed drive, write a

sentinel file to the root partition. After the failed drive is replaced, the file is only readable

if the correct boot drive is replaced.

determine which of the two drives must be replaced.

Procedure

1. Using a serial cable, connect to the node you are going to work on.

2. View boot drive information. Depending on your version of OneFS, run one of the

following commands:
