Evaluating the Status of the Disk Subsystem

You can monitor the disk subsystem by using the CLI command

show hardware_status.

To see a detailed status report, log in to the Infoblox GUI and from the

tab, select the

then click the Detailed Status icon. (For more information, refer to the

Infoblox NIOS Administrator Guide

The color of the RAID icon indicates the status of the RAID array on the appliance.

Color

Meaning

Green

The RAID array is in an optimal state.

Yellow

A new disk was inserted and the RAID array is rebuilding.

Red

The RAID array is degraded. At least one disk is not functioning properly. The GUI lists the disks that are online. Replace only the
disks that are offline.

The Infoblox GUI also displays detailed status of the RAID array. In the event of a disk failure, you must replace the failed disk with one that is
qualified and shipped from Infoblox and has the same disk type as the rest of the disks in the array.
The Infoblox-4030 and Infoblox-4030-10GE appliances display information about mismatched disks in the Description column in the

Detailed Stat

panel. The appliance uses only the IB-Type 3 disk type. All disk drives in the array must have the same disk type for the array to function

us
properly. When you have a mismatched disk in the array, you must promptly replace the disk with a replacement disk from Infoblox to avoid
operational issues.

Note: The replacement IB-Type 3 disk assembly part number is IB-4000-R2-DISK-HDD300.

Disk Array Guidelines

Infoblox designs the disk array to be completely self managed. No maintenance procedures are required for a normally functioning disk array.
Mishandling the disk array may cause an unrecoverable error and result in a failed appliance. Infoblox highly recommends that you observe the
following guidelines:

Remove only one disk at a time. Do not remove two or more disks from the appliance at the same time. Removing two or more disks at
the same time may result in an appliance failure and require an RMA of the appliance. This rule applies to both powered and
powered-down appliances.
If you inadvertently remove the wrong disk drive, do not then immediately remove the disk drive that you originally intended to remove.
Verify the status of the array and replace the disk drive that you initially removed before removing another drive.
If the status of the array is degraded, remove the failed or failing disk drive only. Do not remove an optimally functioning drive.
If your acceptance procedure requires a test of the RAID hot-swap feature, remove only one disk drive at a time. You can remove a
second disk only after you replace the first disk and the array completes its rebuilding process.
Do not remove a disk drive while the array is rebuilding. This may result in an appliance failure. Verify the status of the array before
removing a disk drive.
You can hot-swap a drive while the appliance remains in production.
Some conditions may require powering down the appliance to replace a failed unit. This normally happens if the RAID controller detects
an error that could damage the array. If you insert a replacement drive into a live array and the controller doesn't recognize the drive,
power down the appliance.
All disks in the RAID array must have the same disk type for the array to function properly.
In the unlikely event that two disk drives fail simultaneously and the appliance is still operational, remove and replace the failed disk
drives one at a time.
Rebuild time can vary. The rebuild process takes approximately two hours on an idle appliance. On very busy appliances (over 90%
utilization), the disk rebuild process can take as long as 40 hours. On a Grid Master serving a very large Grid, expect the rebuild process
to take at least 24 hours.
Replace a failed or mismatched disk only with a replacement disk shipped from Infoblox. When you request a replacement disk, report
the disk type displayed in the Detailed Status panel of the Infoblox GUI or the Infoblox part number on the disk.
