• BIOS Conguration Utility — This is also known as Ctrl+R, and is a storage management application that congures and maintains
RAID disk groups and virtual disks. See BIOS Conguration Utility.

• Unied Extensible Firmware Interface (UEFI) RAID Conguration Utility. This storage management application is integrated into the
System BIOS, accessible through the F2 key. See UEFI RAID conguration utility. RAID congurations on NVMe PCIe SSDs are only
supported through the UEFI RAID conguration utility.

NOTE

: Ensure that the RAID mode is enabled for NVMe PCIe SSDs. See Setting the NVMe PCIe SSDs to RAID mode

• OpenManage Storage Management-This application enables you to perform controller and enclosure functions for all supported RAID

Overview

Physical Disks

NOTE: The physical disks in a virtual disk must be of the same drive type (HDD, SSD or NVMe PCIe SSD). For example, you

cannot mix an HDD and an NVMe PCIe SSD in the same virtual disk.

Physical disk features

Physical disk roaming

Physical disk roaming is moving the physical disks from one cable connection or backplane slot to another on the same controller. The
controller automatically recognizes the relocated physical disks and logically places them in the virtual disks, which are part of the disk
group. You can perform disk roaming only when the system is turned o.

CAUTION: Do not attempt disk roaming during online capacity expansion (OCE). This causes loss of the virtual disk.

2

Physical disk hot-swapping

NOTE

: To check if the backplane supports hot swapping, see your system documentation.

Hot-swapping is the manual replacement of a disk while the PERC S140 is online and performing its normal functions. The following
requirements must be met before hot-swapping a physical disk:

• The system backplane or enclosure must support hot swapping for the PERC S140.

• The replacement disk must be of the same protocol and disk technology. For example, only a SATA hard drive can replace a SATA hard
drive and only a SATA SSD can replace a SATA SSD.

NOTE

: Disk hot-swapping is not supported in UEFI mode; it is supported only in OS mode.

NOTE: When hot-swapping a physical disk, ensure that the new disk is of equal or greater capacity to the physical disk that is

being replaced.

Physical disk power management

Power management is a power-saving feature of the PERC S140. This feature supports power management of SATA hard drives (HDD) by
using Extended Power Conditions (EPC). The EPC feature set provides the host with additional methods to control the power condition of
a device.

Physical disk failure detection

Physical disk failure is detected and the controller automatically rebuilds a new physical disk assigned as a hot spare.

: Refer to drive mixing restrictions for rebuilding.

NOTE

Physical Disks 11

Mirror rebuilding

A RAID mirror conguration can be rebuilt after a new physical disk is inserted and the physical disk is designated as a hot spare.

NOTE: The system does not have to be rebooted.

Fault tolerance

The following fault tolerance features are available with the PERC S140:

• Physical disk failure detection (automatic).

• Virtual disk rebuild using hot spares (automatic, if the hot spare is congured for this feature).

• Parity generation and checking (RAID 5 only).

• Hot-swap manual replacement of a physical disk without rebooting the system (only for systems with a backplane that allows hot­swapping).

If one side of a RAID 1 (mirror) fails, data can be rebuilt by using the physical disk on the other side of the mirror.

If a physical disk in RAID 5 fails, parity data exists on the remaining physical disks, which can be used to restore the data to a new
replacement physical disk congured as a hot spare.

If a physical disk fails in RAID 10, the virtual disk remains functional and data is read from the surviving mirrored physical disk(s). A single
disk failure in each mirrored set can be sustained, depending on how the mirrored set fails.

Self-Monitoring And Reporting Technology

The Self-Monitoring and Reporting Technology (SMART) feature monitors certain physical aspects of all motors, heads, and physical disk
electronics to help detect predictable physical disk failures. Data on SMART compliant physical disks can be monitored to identify changes
in values and determine whether the values are within threshold limits. Many mechanical and electrical failures display some degradation in
performance before failure.

A SMART failure is also referred to as a predicted failure. There are numerous factors that are predicted physical disk failures, such as a
bearing failure, a broken read/write head, and changes in spin-up rate. In addition, there are factors related to read/write surface failure,
such as seek error rate and excessive bad sectors.

NOTE

: For detailed information on SCSI interface specications, see t10.org, and for detailed information on SATA interface

specications, see t13.org.

Native Command Queuing

Native Command Queuing (NCQ) is a command protocol used by SATA physical disks supported on the S140 controller. NCQ allows the
host to provide multiple input/output requests to a disk simultaneously. The disk decides the order to process the commands to achieve
maximum performance.

NVMe PCIe SSD support

S140 supports the NVMe PCIe SSD-including the NVMe PCIe SSD 2.5-inch Small Form Factor (SFF) and NVMe PCIe SSD Adapter.

12

Physical Disks

The S140 allows the NVMe PCIe SSD 2.5 inch SFF and the NVMe PCIe SSD adapter in a RAID conguration. The NVMe PCIe SSDs
supports volume, RAID 0, RAID 1, and RAID 10.

NOTE: Hot removal or hot insertion of the NVMe PCIe SSDs in UEFI or pre-boot mode is not supported. In the operating system

environment, hot-swapping two or more NVMe PCIe SSDs simultaneously is not supported.

NOTE: Mixing of SATA drives and NVMe PCIe SSDs in a virtual disk is not supported.

NOTE: Ensure that you use only the S140 UEFI conguration utility to congure the NVMe PCIe SSDs during

preboot.

NOTE: In UEFI HII mode, you can use the NVMe PCIe SSD option on the Device Settings page to view NVMe physical disk

properties and perform blink/unlink operations.

NOTE: RAID conguration and boot from NVMe virtual disk is supported only in UEFI boot

mode.

NOTE: RAID conguration using Option ROM (OPROM) is not supported on systems with the NVMe PCIe

SSD.

Physical disk write cache policy for SATA drives

The physical disk write cache policy feature enables the disk to cache the data rst, and then the cached data is written to the storage
device in the background. For more information about managing the physical disk write cache policy, see

cache policy for SATA drives.

: You can use UEFI or Option ROM (OPROM) to congure the physical disk write cache

NOTE

policy.

NOTE: You cannot congure a physical disk write cache policy on a non-RAID

disk.

NOTE: Linux RAID does not support conguring physical disk write cache policy, or virtual disk write cache

policy.

Managing the physical disk write

Linux RAID

The Linux RAID feature is supported on all PowerEdge 14th generation systems. You can use Linux RAID to protect data across multiple
devices. The S140 conguration utility supports conguring RAID 1 virtual disk in UEFI mode. The Linux operating system can be installed
on that virtual disk, and once the system boots to the Linux environment, the Linux native RAID driver manages the virtual disk. For
information about conguring Linux RAID, see Conguring Linux RAID.

NOTE

: Ensure that your system has the latest BIOS rmware. You can download the latest BIOS rmware from dell.com/

support.

NOTE: Ensure that you use only the S140 UEFI conguration utility to congure Linux RAID feature during pre-

boot.

NOTE: Ensure that the boot virtual disks are congured in RAID 1, using two physical disks of identical drive type (HDD or SSD)

and sector size. However, you can also congure nonboot virtual disks in any of the supported RAID levels in the Linux operating
system.

Physical Disks 13

Virtual Disks

A logical grouping of physical disks attached to a PERC S140 allows you to create multiple virtual disks of the same RAID levels, without
exceeding a maximum of 16 virtual disks.

The PERC S140 controller allows:

• Creating virtual disks of dierent RAID levels on a S140 controller.

NOTE: Ensure that you do not mix RAID levels on the same physical disks.

• Building dierent virtual disks with dierent characteristics for dierent applications.

• Creating virtual disks from a mix of NVMe PCIe SSD 2.5-inch SFFs and NVMe PCIe SSD adapters.

The PERC S140 controller does not allow:

• Creating a virtual disk from a mix of dierent types of physical disks. For example, a RAID 10 virtual disk cannot be created from two
SATA HDD physical disks and a SATA SSD physical disk. All of the physical disks must be of the same drive type (HDD/SSD/NVMe
PCIe SSDs).

• Selecting a physical disk as a dedicated hot spare if the physical disk is a dierent type from the physical disk of the virtual disks.

A virtual disk refers to data storage which a controller creates using one or more physical disks.

3

NOTE

: A virtual disk can be created from several physical disks; the operating system considers it a single disk.

The capacity of a virtual disk can be expanded online for any RAID level without rebooting the operating system.

Virtual disk features

TRIM for SATA SSDs

The TRIM command allows an operating system to delete a block of data that is no longer considered in use from the SATA SSDs. TRIM
resolves the Write Amplication issue for supported operating systems. When an operating system deletes a le, the le is marked for
deletion in the le system, but the contents on the disk are not actually erased. As a result, the SSDs do not know that the Logical Block
Addressing (LBA) le previously occupied can be erased. With the introduction of TRIM, when a le is deleted, the operating system sends
a TRIM command along with the LBAs that do not contain valid data.

NOTE

: The TRIM feature is supported only on pass-through SSDs.

NOTE: The TRIM feature is not supported on NVMe PCIe SSDs.

To perform TRIM on the pass-through SSDs

1 Create a volume on a pass-through SSD drive.

2 In the Windows operating system, navigate to the Defragmentation and Optimize Drive tool.

3 Select the volume created on the pass-through SSD and click the Optimize button.

The volume is trimmed.

14 Virtual Disks

Disk initialization

For physical disks, initialization writes metadata to the physical disk so that the controller can use the physical disk.

Background Array Scan

Veries and recties correctable media errors on mirror, volume, or parity data for virtual disks. Background Array Scan (BAS) starts
automatically after a virtual disk is created while in the operating system.

Checkpointing

Allows dierent types of checkpointing to resume at the last point following a restart. After the system restarts, background checkpointing
resumes at its most recent checkpoint.

Three types of checkpointing are available:

• Consistency check (CC)

• Background initialization (BGI)

• Rebuild

Consistency check

Consistency check (CC) is a background operation that veries and corrects the mirror or parity data for fault-tolerant physical disks. It is
recommended that you periodically run a consistency check on the physical disks.

By default, CC corrects mirror or parity inconsistencies. After the data is corrected, the data on the primary physical disk in a mirror set is
assumed to be the correct data and is written to the secondary physical disk mirror set.

The CC operation reports data inconsistencies through an event notication. A CC cannot be user-initiated in the BIOS Conguration Utility
(Ctrl+R). However, CC can be initiated using OpenManage Server Administrator Storage Management. For more information, see OMSA
user’s guide at dell.com/openmanagemanuals.

Background initialization

Background initialization (BGI) of a redundant virtual disk creates the parity data that allows the virtual disk to maintain its redundant data
and survive a physical disk failure. Similar to consistency check (CC), BGI helps the controller to identify and correct problems that might
occur with the redundant data at a later time.

CAUTION

BGI allows a redundant virtual disk to be used immediately.

NOTE

S140 drivers must be loaded before the BGI runs.

: Data is lost if a physical disk fails before the completion of a BGI operation.

: Although a BGI is software-initiated from within the BIOS Conguration Utility (accessible through Ctrl + R), the PERC

Automatic virtual disk rebuild

Rebuilds a redundant virtual disk automatically when a failure is detected if a hot spare is assigned for this capability.

Virtual Disks

Virtual disk cache policies

NOTE: Conguring virtual disk cache policies on NVMe PCIe SSD is not

supported.

The PERC S140 uses part of system memory for cache. It supports the following cache options:

• Read Ahead/Write Back

• No Read Ahead/Write Back

• Read Ahead/Write Through

• No Read Ahead/Write Through

Table 6. Read, Write, and Cache Policy for the PERC S140

Category Supported by S140 controller

Cache settings Yes

Read Ahead/Write Back Yes

No Read Ahead/Write Back Yes

NOTE: The current default for Write-Cache mode enablement is Write Through, No Read Ahead (WT, NRA). To enable Write

Back (WB), a UPS is recommended.

NOTE: For more information about the physical disk write cache policy behavior, see Troubleshooting your system

Virtual disk migration

The PERC S140 supports automatic virtual disk migration from one PERC S140 to another.

CAUTION

Recongure.

NOTE: Back up the virtual disk data before migrating virtual disks.

NOTE: Ensure that all physical disks that are part of the virtual disk are migrated. Virtual disks in optimal and degraded states are

automatically migrated. A virtual disk in an oine state should not be migrated.

NOTE: A bootable virtual disk cannot be migrated between dissimilar system models.

NOTE: When you migrate virtual disks, ensure that you verify that the number of virtual disks does not exceed 10.

Migrating a virtual disk

1 Turn o the system that contains the source controller.

2 Turn o the target system if the system does not support hot swap of physical disks.

3 Move the appropriate physical disks from the source controller to the target controller in the target system.

Physical disks do not have to be inserted into the same slots in the target system.

Virtual Disks

4 If the target system was turned o, turn on the system.

CAUTION: The BIOS Conguration Utility pauses, and prompts for action, for the degraded virtual disk(s), if the "pause if

degraded" option is enabled in the BIOS Conguration Utility.

CAUTION: After the migration occurs, ensure that all of the physical disks have been migrated and are present in the appropriate

virtual disks.

Expanding virtual disk capacity

The capacity of a virtual disk can be expanded online by using the Online Capacity Expansion/Recongure (OCE/Recongure). OCE/
Recongure is a process that allows you to add storage capacity to an existing virtual disk. In most cases additional storage capacity can be
added without taking the system oine.

NOTE: If an additional physical disk is required and the system does not support hot-swapping, the system must be turned

o.

OCE/Recongure enables you to increase the total storage capacity of a virtual disk by integrating unused storage with the virtual disk.

Data can be accessed while the physical disks are added (if a system has hot-swap capability) and while data on the virtual disk is being
redistributed.

For volume, RAID 1, and RAID 10, OCE/Recongure expands the virtual disk by using the available space of the physical disks, which have
been members of the virtual disk. For RAID 0 and RAID 5, additional capacity can be attained by adding physical disks to the virtual disk.

Assigning the dedicated hot spare disks

A dedicated hot spare is a backup physical disk for the redundant virtual disk to which it is assigned. The physical disk that is used as a
dedicated hot spare cannot be a member of an existing virtual disk. When the hot spare is activated, it becomes the receptacle for the data
from the failed physical disk member of the volume, without interrupting the system or requiring your intervention. A dedicated hot spare
can be assigned to any redundant virtual disk, and up to four hot spares can be assigned to a virtual disk. A dedicated hot spare cannot be
assigned while a task is running on the virtual disk.

NOTE: A virtual disk is marked Failed or Degraded if a physical disk reports a Failed state, or if the SAS/SATA cable to the

physical disk or power cable is disconnected.

Warning Messages

The Dell Inc. PERC S140 Controller system BIOS screen is one of the rst screens to appear during your system’s boot sequence. If the
system’s virtual disks were in Normal or Ready status before a system boot, the boot sequence continues normally to the Microsoft
Windows Server operating system. But, if a virtual disk is in Degraded or Failed status, or if specic options in the Controller Options eld
were changed previously at the BIOS Conguration Utility (<Ctrl><R>), the following warning messages appear during the boot
sequence.

WARNING- Found virtual disks that are degraded

This warning message is displayed when at least one virtual disk is in a Degraded state and Pause if Degraded is set to ON at the BIOS

Conguration Utility Ctrl+R.

46

Troubleshooting your system

The following message is displayed after the warning is displayed: --- Press Enter to continue, or Ctrl+R to enter setup ---.

Press Enter to allow the operating system to continue with the boot sequence, or press Ctrl+R to enter into the BIOS Conguration Utility
Ctrl+R to investigate the cause of the Degraded virtual disk.

To investigate the cause, check for the following:

• Whether a physical disk in the virtual disk has failed or has gone oine. Check the status at the Physical Disks eld. A Degraded status
depends on the RAID level of the virtual disk and the number of physical disks that have failed:

–For a virtual disk at RAID 1 or RAID 5, a single physical disk failure causes a Degraded status.

–For a virtual disk at RAID 10, the failure of a physical disk in each of the mirror sets creates a Degraded status for the RAID 10. The
failure of two physical disks in the same mirror set creates a Failed status for the RAID 10.

• Whether the controller has failed due to a rmware failure or a component failure. A failed controller causes a virtual disk not to boot.

For the virtual disk to recover from Degraded status, the failed physical disk must be replaced and the virtual disk must be rebuilt using
OpenManage Server Administrator Storage Management. When the rebuild operation is completed, the virtual disk status changes from

Degraded to Ready. For a description of the rebuild function, see Storage Management at dell.com/support/manuals.

WARNING - Found virtual disks that are failed

This warning message is displayed when at least one virtual disk is in a Failed state and Pause if Failed is set to ON at the BIOS

Conguration Utility (<Ctrl><R>).

The following message is displayed after the warning is displayed: --- Press <Enter> to continue, or <Ctrl><R> to enter setup --- .

Press <Enter> to allow the operating system to continue its boot, or press <Ctrl><R> to enter into the BIOS Conguration Utility

(<Ctrl><R>) to investigate the cause of the Failed virtual disk.

NOTE

: A boot virtual disk that is in a Failed state prevents the operating system from booting.

To investigate the cause, check for the following:

• Determine if a single or multiple physical disks in a non-redundant virtual disk have failed. If yes, data is lost. Recover the lost data from
a backup storage source.

• Determine if two or more physical disks in a redundant virtual disk have failed. If yes, data is lost. Recover the lost data from a backup
storage source.

NOTE

: For a RAID 10 conguration, if a single physical disk fails in each mirrored set, the redundant virtual disk goes to a

Degraded status but data is not lost. If two physical disks fail in one of the mirrored sets, the redundant virtual disk goes to a
Failed status and data is lost.

WARNING - Found virtual disks that are degraded and failed

This warning message is displayed when multiple virtual disks are in Degraded and Failed state and Pause if Degraded or Pause if Failed
are set to ON at the BIOS Conguration Utility Ctrl+R.

The following message is displayed after the warning is displayed: --- Press Enter to continue, or Ctrl+R to enter setup --- .

Press <Enter> to allow the operating system to continue its boot, or press Ctrl+R to enter into the BIOS Conguration Utility Ctrl+R to
investigate the cause of the Degraded and Failed virtual disks.

Troubleshooting your system

47

NOTE: A boot virtual disk that is in a Failed state prevents the operating system from booting.

To investigate the cause, check for the following:

• Whether the virtual disk is in Degraded status because one of the physical disks of a RAID 1 or RAID 5 virtual disk has failed, or one of
the physical disks of a RAID 10 virtual disk has failed. Press Ctrl+R and verify if the physical disks are oine or missing. Remove and
replace a failed physical disk. A second physical disk failure could cause a Degraded virtual disk to change to Failed status.

• Whether the virtual disk is in a Failed status because one or more of the physical disks have failed. Press Ctrl+R and verify if the
physical disks are oine or missing. Remove and replace the failed physical disk or disks.

Virtual disks - Related errors

Cannot create a virtual disk

If you are unable to create a virtual disk, check the following causes:

1 The physical disk is not displayed.

2 Insucient free space available on the selected physical disks.

3 Incorrect number of physical disks selected for the desired RAID level .

4 The desired physical disk is unavailable.

5 The system already has a maximum of 16 virtual disks.

50

Troubleshooting your system

The physical disk is not displayed

This error might be because:

1 The controller cannot communicate with the physical disks.

2 A cable might be loose or defective.

3 The physical disk might be a SAS drive.

Re-seat the physical disks in the backplane and check their cables.

Insucient free space available on the selected physical disks

There must be sucient available free space on the physical disk used by the virtual disk.

Incorrect number of physical disks selected for the desired RAID level

For details about RAID levels and the allowable number of physical disks used with each RAID level, see understanding RAID levels in RAID
Technology Guide at dell.com/support/manuals.

The desired physical disk is unavailable

Determine whether the physical disk:

1 Is a dedicated hot spare and unavailable for use in another virtual disk.

2 Is full or has insucient available capacity.

The system already has a maximum of 16 virtual disks

Delete unused virtual disks.

CAUTION

: Deleting a virtual disk destroys all data on the virtual disk.

A virtual disk is in a degraded state

If the virtual disk is in a degraded state, check the following causes:

1 A physical disk was removed.

2 Physical or mechanical problems with the physical disk.

3 The virtual disk has lost redundancy.

4 Corrupted metadata in the virtual disk.

A physical disk was removed

1 Install the original physical disk if it was inadvertently removed, or replace it with a new or used physical disk.

2 Initialize a new physical disk. Perform a Rescan for all physical disks that are replaced.

3 If the physical disk was not removed, check that its cables are correctly installed.

Troubleshooting your system

51

Physical or mechanical problems with the physical disk

1 Determine if the physical disk in the virtual disk has failed.

2 If a physical disk was recently removed and replaced, determine that it is correctly positioned in the backplane. Check the cable

connections at the physical disk and at the system board.

3 Perform a Rescan

The virtual disk has lost redundancy

One or more physical disks in the virtual disk may have failed, due to the failed physical disk or disks, the virtual disk is no longer maintaining
redundant (mirrored or parity) data. The failure of an additional physical disk results in lost data.

1 Replace the physical disk or disks.

2 Rebuild the physical disk using Storage Management. See the applicable Storage Management screen at dell.com/support/manuals.

Corrupted metadata in the virtual disk

1 Delete the virtual disk that has the failed metadata.

2 Assign the physical disk as a hot spare to rebuild a redundant virtual disk.

3 To create a non-redundant virtual disk, delete and rebuilt the data on a virtual disk, and restore the data from a backup storage source.

Cannot assign a dedicated hot spare to a virtual disk

If you cannot assign a dedicated hot spare to a virtual disk, check the following causes:

1 The RAID level does not allow a dedicated hot spare to be created.

2 The designated physical disk does not have sucient capacity to be a dedicated hot spare.

3 The physical disk is already part of a virtual disk.

4 The physical disk are of dierent types.

The RAID level does not allow a dedicated hot spare to be created

Hot spares cannot be created for Volume or RAID 0 virtual disks.

The designated physical disk does not have sucient capacity to be a
dedicated hot spare

The capacity of the physical disk selected to be a dedicated hot spare must be equal to or larger than the capacity of the smallest physical
disk in the virtual disk. For example, if the physical disk selected for a dedicated hot spare is 160 GB, and the physical disks in the virtual
disk are 80 GB, 160 GB, and 500 GB, a dedicated hot spare can be assigned. That is because the physical disk selected for the dedicated
hot spare is larger than the smallest (80 GB) physical disk in the virtual disk.

The physical disk is already part of a virtual disk

A dedicated hot spare cannot be assigned to another virtual disk.

52

Troubleshooting your system

The physical disk are of dierent types

The physical disk used as a dedicated hot spare must be the same type as the physical disks that are already part of the virtual disk. For
example, if a virtual disk consists of SATA-II physical disks, the dedicated hot spare must be a SATA-II physical disk.

Cannot create a global hot spare

If you cannot create a global hot spare, check the following causes:

1 There are no empty physical disks available or the physical disks have not been converted to RAID-capable disks.

2 The physical disk is already part of a virtual disk.

3 The physical disk assigned as the global hot spare has failed.

4 The physical disk assigned as the global hot spare is missing.

There are no empty physical disks available or the physical disks have not
been converted to RAID-capable disks

Install additional physical disks and convert them to a RAID-capable disk, If existing physical disks are Non-RAID they need to be converted
to RAID-capable disks.

WARNING

NOTE: A physical disk with a Non-RAID status can be converted to a RAID-Capable disk, if desired, but it is no longer Non-RAID

(Converting to RAID-Capable adds PERC S140 conguration information to the physical disk).

: When a physical disk is converted to RAID Capable disks, all data on the physical disk is lost.

The physical disk is already part of a virtual disk

A hot spare cannot be selected if it is already part of an existing virtual disk.

The physical disk assigned as the global hot spare has failed

When prompted at system startup, press Ctrl+R to access the BIOS Conguration Utility Ctrl+R. In the BIOS Conguration Utility Ctrl

, select View Virtual Disk Details and press Enter. Determine whether the physical disk that is designated as the global hot spare has a

+R

status of Failed.

1 Check to see if the physical disk is malfunctioning or is physically disconnected.

2 Select another physical disk as the global hot spare.

The physical disk assigned as the global hot spare is missing

• Check to see if the physical disk was removed from the backplane or cable connection, or whether the cables from the controller to the
physical disk are disconnected or faulty.

• Perform a rescan to verify that the physical disk is still missing.

Troubleshooting your system

53

A dedicated hot spare fails

If a dedicated hot spare fails, check the following causes:

1 The controller cannot communicate with the hot spare.

2 The dedicated spare is not visible in the BIOS Conguration Utility or is oine.

The controller cannot communicate with the hot spare

1 Check that the cable from the controller to the physical disk is connected properly.

2 Ensure that the physical disk is still assigned as a global or dedicated hot spare.

3 Determine if the physical disk assigned as the hot spare has failed.

The dedicated spare is not visible in the BIOS Conguration Utility or is
oine

1 Determine if the physical disk has been removed or has failed.

2 Check for a loose or bad cable.

Failed or degraded virtual disk

The removal of one physical disk from a virtual disk causes:

1 A volume or RAID 0 virtual disk to change to Failed status.

2 A RAID 1 and RAID 5 virtual disk to change to Degraded status.

3 A RAID 10 virtual disk to change to Degraded status (when a physical disk is removed from one of the mirrored sets).

Re-insert the removed physical disk and perform a Rescan of the virtual disk.

Cannot create a virtual disk on selected physical disks

Determine whether these physical/virtual disks were migrated from a legacy controller with mixed RAID levels. If so, creating additional
virtual disk on these physical disk is not allowed.
