Identifying the series of your Dell EMC PowerEdge servers

● Virtual disk or logical drive size is smaller than expected.

If you have created a virtual disk that exceeds the 1TB limitation, you must:

1. Back up your data.

2. Delete the virtual disk.

3. Create one or more virtual disks that are smaller than 1TB.

4. Restore your data from backup.

Irrespective of whether your Linux operating system limits the virtual disk size to 1TB, the virtual disk size depends on the

version of the operating system and any updates or modifications that you have implemented. For more information on

operating system, see your operating system documentation.

Problems Associated With Using The Same Physical Disks For Both

Redundant And Non-Redundant Virtual Disks

When creating virtual disks, you should avoid using the same physical disks for both redundant and nonredundant virtual disks.

This applies to all controllers. Using the same physical disks for both redundant and nonredundant virtual disks can result in

unexpected behavior including data loss.

NOTE: SAS controllers do not allow you to create redundant and nonredundant virtual disks on the same set of physical

disks.

Specific Problem Situations And Solutions

This section contains additional troubleshooting information. Topics include:

● Physical Disk Is Offline Or Displays An Error Status

● Receive A Bad Block Alert With Replacement, Sense, Or Medium Error

● Read And Write Operations Experience Problems

● A Task Menu Option Is Not Displayed

● A Corrupt Disk Or Drive Message Suggests Running Autocheck During A Reboot

● Erroneous Status And Error Messages After A Windows Hibernation

● Storage Management May Delay Before Updating Temperature Probe Status

● Storage Management May Delay Displaying Storage Devices After Reboot

● You Are Unable To Log Into A Remote System

● Cannot Connect To Remote System Running Microsoft Windows Server 2003

● Reconfiguring A Virtual Disk Displays Error In Mozilla Browser

● Physical Disks Are Displayed Under The Connector Object Instead Of The Enclosure Object

Physical Disk Is Offline Or Displays An Error Status

A physical disk may display an error status if it has been damaged, is offline, or was a member of a virtual disk that has been

deleted or initialized. The following actions may resolve the error condition:

● If a user has changed the status to Offline, then return the disk to Online status by performing the Online disk task.

● Investigate whether there are any cables, enclosure, or controller problems preventing the disk from communicating with the

controller. If you find a problem and resolve it and disk does not return to Online or Ready status, reboot the system.

● If the disk is damaged, replace it.

Receive A Bad Block Alert With Replacement, Sense, Or Medium

Error

The following alerts or events are generated when a portion of a physical disk is damaged:

● 2146

● 2147
