Dell PowerVault MD3420 - Manual (Page 21)

Expanding With Previously Configured PowerVault MD1200 Series Expansion
Enclosures
CAUTION: If a PowerVault MD1200 series expansion enclosure that was previously attached to a
PERC H800 adapter is used as an expansion enclosure to a PowerVault MD series storage array,
the physical disks of the expansion enclosure are reinitialized and data is lost. You must back up
all data on the expansion enclosure before attempting the expansion.
Use this procedure if your expansion enclosure is directly attached to and configured on a Dell
PowerEdge RAID Controller (PERC) H800 adapter. Data from virtual disks created on a PERC H800
adapter cannot be directly migrated to a PowerVault MD series storage array or to a PowerVault MD1200
series expansion enclosure connected to a PowerVault MD series storage array.
To attach previously configured PowerVault MD1200 series expansion enclosures to the PowerVault
MD3400 or PowerVault MD3420 storage array:
1. Back up all data on the expansion enclosures.
2. Upgrade the expansion enclosure firmware to the latest version available at dell.com/support while
the enclosure is still attached to the PERC H800 controller.
Windows systems users can reference the DUP.exe package and Linux kernel users can reference
the DUP.bin package.
3. Ensure that the storage array software is installed and up to date before adding the expansion
enclosures. For more information, see the Dell PowerVault MD34xx/38xx Series Support Matrix at
dell.com/support/manuals.
a) Install the software and driver package from the PowerVault MD series resource media. For
information about installing the software, see Installing PowerVault MD Storage Software .
b) Update the storage array RAID controller module firmware and NVSRAM to the latest versions
available at dell.com/support.
c) Using MDSM, click Tools → Upgrade RAID Controller Module Firmware → Enterprise
Management Window (EMW).
4. Stop all I/O and turn off the system and attached units.
a) Turn off the storage array.
b) Turn off the expansion enclosures.
5. Cable the expansion enclosures to the storage array.
a) Connect the MiniSAS HD end of the supported SAS cabled to the SAS OUT Port 0 on the MD
1200 series array.
b) Connect the other end of the SAS cable to the IN port on the MD 1200 series array.
6. Turn on the attached units:
a) Turn on the expansion enclosures. Wait for the enclosure status LEDs to light blue.
b) Turn on the storage array and wait for the status LEDs to indicate that the unit is ready:
* If the status LEDs are solid amber, the storage array is still coming online.
* If the status LEDs are blinking amber, there is an error that can be viewed using the MDSM.
* If the status LEDs are solid blue, the storage array is ready.
c) After the storage array is online and ready, turn on any attached host systems.
7. After the PowerVault MD1200 series expansion enclosure is configured as an expansion enclosure of
the storage array, restore the data that was backed up in step 1.
After the expansion enclosures are online, they can be accessed as a part of the storage array.
