Cabling Your RAID Enclosure
For a more detailed discussion of redundancy and nonredundancy, as well as alternate path software, see
"Hardware Redundancy and Failover" on page 49.
Attaching MD1000 Expansion Enclosures
One of the features of the MD3000 is the ability to add up to two MD1000 expansion enclosures for
additional capacity. This expansion increases the maximum physical disk pool to 45 3.5" SAS physical
disks.
As described in the following sections, you can expand with either a new MD1000 or an MD1000 that
has been previously configured in a direct-attach solution with a PERC 5/E system.
NOTICE:
Ensure that all MD1000 expansion enclosures being connected to the MD3000 are updated to the latest
Dell MD1000 EMM Firmware from support.dell.com. Dell MD1000 EMM Firmware version A00 is not supported in an
MD3000 array; attaching an MD1000 with unsupported firmware causes an uncertified condition to exist on the
array. See the following procedure for more information.
Expanding with Previously Configured MD1000 Enclosures
Use this procedure if your MD1000 is currently directly attached to and configured on a Dell PERC 5/E
system. Data from virtual disks created on a PERC 5 SAS controller cannot be directly migrated to an
MD3000 or to an MD1000 expansion enclosure connected to an MD3000.
NOTICE:
If an MD1000 that was previously attached to PERC 5 SAS controller is used as an expansion enclosure
to an MD3000, the physical disks of the MD1000 enclosure will be reinitialized and data will be lost. All MD1000 data
must be backed up before attempting the expansion.
Perform the following steps to attach previously configured MD1000 expansion enclosures to the
MD3000:
1 Back up all data on the MD1000 enclosure(s).
2 While the enclosure is still attached to the PERC 5 controller, upgrade the MD1000 firmware to an
A03 or higher configuration. Windows systems users can reference the DUP.exe package; for Linux
kernels, users can reference the DUP.bin package.
3 Before adding the MD1000 enclosure(s), make sure the MD3000 software is installed and up to date.
