Dell EMC Server Administrator Storage Management 9.3.1 User’s Guide

— Normal/OK

— Warning/Non-critical

— Critical/Failure/Error

NOTE: : Power status of SAS/SATA SSD showing as Not Applicable is an expected behaviour in Storage Management.

For all the disks which are not part of the virtual disk will display as NON-Raid Disks for systems running on Enhanced HBA mode. Hot-plugged in disks also displays as NON-RAID disks.

• Ready — The physical disk or device is functioning normally. If the disk is attached to a RAID controller Ready indicates that the disk is available to be used by a virtual disk. When the physical disk or device is used in a virtual disk, the state changes to Online.
• Online — Indicates that the physical disk is part of a virtual disk and is functioning normally. For more information, see Setting Online And Offline.

  NOTE: : For all NON-Raid Disks for systems running on Enhanced HBA mode will have the status displayed as Online.

• Degraded — The physical disk or device has encountered a failure and is operating in a Degraded state.
• Failed — The physical disk or device has encountered a failure and is no longer functioning. This state is also displayed when a physical disk or device that is part of a redundant virtual disk is offline or deactivated. For more information, see Setting Online And Offline.
• Offline — The physical disk or device has failed or contains dead segments. Check to see if the Remove Dead Segments task appears on the physical disk drop-down menu. Refresh the system and then remove the dead segment (Removing Dead Segments) for the physical disk. If this task is not displayed, then the physical disk or device cannot be recovered.
• Rebuilding — Data from a redundant virtual disk is being rebuilt onto the physical disk or device.
• Incompatible — The physical disk or device is not suitable for a rebuild. The physical disk or device may be too small or it may be using an incompatible technology. For example, you cannot rebuild a SAS disk with a SATA disk or a SATA disk with a SAS disk.
• Removed — The physical disk or device has been removed. This state applies only to physical disks that are part of a virtual disk.
• Clear — The Clear task is being performed on the physical disk or device. A physical disk or device may also display the Clear state if the physical disk or device is a member of a virtual disk that is being slow initialized. For more information, see Performing A Clear Physical Disk And Cancel Clear and Slow And Fast Initialize.
• SMART Alert Detected — A SMART alert (predictive failure) has been detected on the physical disk or device. The physical disk or device may fail and should be replaced. This state applies to physical disks or devices attached to non-RAID and M.2 device controllers.
• Unknown — The physical disk or device has failed or is in an unusable state. At times, the physical disk or device can be returned to a usable state by performing a Format, Initialize, Slow, And Fast Initialize task. If the Format, Initialize, Slow, And Fast Initialize task does not appear on the physical disk or device drop-down menu, then this disk or device cannot be recovered.
• Foreign — The physical disk has been moved from another controller and contains all or some portions of a virtual disk (foreign configuration). A physical disk or device that has lost communication with the controller due to a power loss, faulty cable or other failure event may also display the Foreign state. For more information, see Foreign Configuration Operations.
• Unsupported — The physical disk or device is using an unsupported technology or it may not be certified by your service provider. The physical disk cannot be managed by Storage Management.
• Replacing — A Replace Member Disk task is being performed on the physical disk or device. For more information, see Replacing A Member Disk and Enabling Revertible Hot Spare.

  NOTE: : You can cancel the copying of data at any time during the execution of this task.

• Non-RAID — Non-RAID disks are exposed to the operating system unlike unconfigured disks and enables usage of disk in direct pass-through mode. Maximum number of non-RAID disks that can be supported on H310 controller are 64.

• SAS
• SATA

• HDD — Hard Disk Drive. An HDD is a nonvolatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.
• SSD — Solid-State Drive. An SSD is a data storage device that uses solid-state memory to store persistent data.
• Unknown — Storage Management is unable to determine the media type of the physical disk or device.

NOTE: : This option is applicable to Micron PCIe SSDs, Non-Volatile Memory Express (NVMe) PCIe SSDs, M.2 devices and SAS/SATA SSDs.

In certain circumstances, the Used RAID Disk Space displays a value of zero even though a portion of the physical disk or device is being used. This occurs when the used space is 0.005GB or less. The algorithm for calculating the used disk space rounds a figure of 0.005GB or less to 0. Used disk space that is between 0.006GB and 0.009GB is rounded up to 0.01GB.

NOTE: : This feature is not available from PERC 10 or later.
