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 EMC 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:
Back up all data on the expansion enclosures.
Upgrade the expansion enclosure firmware to
the latest version available at
Dell.com/support while the
enclosure is still attached to the PERC H800 RAID controller.
Windows systems users can reference the
DUP.exe package and Linux kernel users can reference the
DUP.bin package.
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.
Install the software and driver package
from the PowerVault MD series resource media. For information about
installing the software, see the
Installing PowerVault MD Storage
Software
section.
Update the storage array RAID controller
module firmware and NVSRAM to the latest versions available at
Dell.com/support.
Stop all I/O and turn off the system and attached
units.
Turn off the storage array.
Turn off the expansion enclosures.
Cable the expansion enclosures to the storage
array.
Connect the MiniSAS HD end of the supported
SAS cabled to the SAS OUT Port 0 on the MD 1200 series array.
Connect the other end of the SAS cable
to the IN port on the MD 1200 series array.
Turn on the attached units:
Turn on the expansion enclosures. Wait
for the enclosure status LEDs to light blue.
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.
After the storage array is online and ready,
turn on any attached host systems.
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.
