SCOM “File system error or corruption” alert.
Summary
NTFS has
reported that the logical disk is either corrupted or completely unavailable.
Some data stored on the volume may be inaccessible.
Causes
A logical disk
may become corrupted or inaccessible due to a number of reasons some of which
include:
•
|
A
physical disk related to the logical disk has been removed or failed
|
•
|
A
physical disk related to the logical disk has become corrupt (for example;
bad sectors) or inoperable
|
•
|
The
disk driver may've encountered an issue
|
Resolutions
Check the status
of your hardware for any failures (for example, a disk, controller, cabling
failure). In most cases, the system log contains additional events from the
lower-level storage drivers that indicate the cause of the failure.
After you have
isolated and resolved the hardware problem:
1. Open the Disk
Management snap-in.
2. Rescan the
disks and then reactivate any disks with errors.
Resynchronize or
regenerate the volume as necessary if the disk was a member of a mirrored or
RAID-5 volume.
3. Run chkdsk on
any reactivated volumes.

Guideline to using Lifecycle Controller on DELL Server
Guideline to using Lifecycle Controller on
DELL Server.
Step 1. Launch the Unified Server Configurator by
rebooting the server and selecting “System Services” or F10 at the DELL boot
screen.
Step 2. Select “Platform Update”. Then select “Launch Platform Update”. If
prompted to configure network, proceed and enter a static IP address. (Proxy
already allowed for FTP to DELL on Universal)
Step 3. On the next screen select FTP Server and input proxy server
settings if needed..
Step 4. Click
Next and you will be presented with a window stating “Please wait while remote
repo is verified”. Although the window states “3 minutes” it can take up to 10
minutes for the process to complete, so don’t reset the server thinking its
locked up.
Step 5. On the
next screen you will be presented with a list of available updates for your
server. As shown in the below window.. Select them individually and click
“Apply” (if multiple is ran simultaneously server update may fail as they have
a timeout period)
Step 6. You will be sitting at a screen showing “Please wait”. You may sit
at this screen for 20 minutes while the files are being downloaded from the FTP
and stored in memory. (no hard drives are needed for this process!).
Step 7. The process will then begin updating hard ware in the server.
Step 8. The system may reboot and enter Lifecycle Controller again to
continue the update process by updating hardware and bios etc. Repeat till all
relevant firmware is updated.
Step 10. Once
this process finalized you can reboot the server and it will boot up to your
ESXi installation.
