• If you have any other types of expansion enclosures, this operation causes the appropriate LED on all of the physical disks in the
expansion enclosure to blink.
To locate the expansion enclosure:
1. Select the Hardware tab.
2. Select a physical disk in the expansion enclosure that you want to locate.
3. Select Hardware > Blink > Expansion Enclosure.
The LED or LEDs on the expansion enclosure or physical disks come on.
4. When you have located the expansion enclosure, click OK.
The LEDs stop blinking. (If you have an expansion enclosure with a blue LED, the LED goes off). If any other blink operations (Blink
Storage Array, Blink Disk Group, Blink Physical Disk Ports, Blink Expansion Enclosure, or Blink Physical Disk) are currently being invoked
from another storage management station, these LEDs also stop blinking.
5. If the LEDs on the expansion enclosure do not stop blinking, from the AMW, select Hardware > Blink > Stop All Indications.
If the LEDs successfully stop blinking, a confirmation message is displayed.
6. Click OK.
Capturing state information
Use the Capture State Information option to capture information about the current state of your storage array and save the captured
information to a text file. You can then send the captured information to your Technical Support representative for analysis.
CAUTION: Potential to cause an unresponsive storage array – The Capture State option can cause a storage array to
become unresponsive to both the host and the storage management station. Use this option only under the guidance of
your Technical Support representative.
1. From the AMW, select Monitor > Health > Capture State Information.
2. Read the information in the Confirm State Capture dialog, and type yes to continue.
3. In the Specify filename text box, enter a name for the file to be saved, or browse to a previously saved file if you want to overwrite
an existing file.
Use the convention filename.dmp for the name of the file. The suffix .dmp is added to the file automatically if you do not specify a
suffix for the file.
4. Click Start.
NOTE:
Each test shows a status of Executing while it is in progress. The test then shows Completed when it
successfully finishes. If any of the tests cannot be completed, a Failed status is displayed in the Execution summary
window.
5. Monitor the progress and completion status of all the tests. When they finish, click OK to close the State Capture dialog.
Clicking Cancel stops the state capture process, and any remaining tests do not complete. Any test information that has been
generated to that point is saved to the state capture file.
SMrepassist utility
SMrepassist (replication assistance) is a host-based utility for Windows platforms. This utility is installed with MD Storage Manager. Use
this utility before and after you create a virtual disk copy on a Windows operating system to ensure that all the memory-resident data for
file systems on the target virtual disk is flushed and that the driver recognizes signatures and file system partitions. You can also use this
utility to resolve duplicate signature problems for snapshot virtual disks.
From a command prompt window on a host running Windows, navigate to: C:\Program Files\Dell\MD Storage Manager
\util and run the following command:
SMrepassist -f <filesystem-identifier>
Where, -f flushes all the memory-resident data for the file system indicated by <filesystem-identifier>, and <filesystem-identifier>,
specifies a unique file system in the following syntax: drive-letter:<mount-point-path>
The file system identifier may consist of only a physical disk letter, as in the following example:
SMrepassist -f E:
NOTE: In Windows, the mount point path is a physical disk letter.
