Before You Begin
Verify that the following tasks have been completed for your cluster:
• All hardware is installed in the rack.
• All hardware interconnections are configured.
• All virtual disks/LUNs, RAID groups, and storage groups are created
on the storage system.
• Storage groups are assigned to the cluster nodes.
CAUTION: Before you perform the procedures in the following sections, ensure that
the system hardware and cable connections are installed correctly.
Cabling Your SAS Storage System
Because SAS clusters can only be installed in a direct-attached cluster, they are
limited to two nodes only.
To configure your nodes in a direct-attached configuration (see
Figure 4 ),
complete the following steps:
1
Connect one SAS cable from a port of the SAS controller of node 1 to the In-0
port of RAID controller 0 in the MD3000 RAID enclosure.
2 Connect one SAS cable from a port of the other SAS controller of node 1 to
the In-0 port of RAID controller 1 in the MD3000 RAID enclosure.
3 Connect one SAS cable from a port of the SAS controller of node 2 to the In-1
port of RAID controller 0 in the MD3000 RAID enclosure.
4 Connect one SAS cable from a port of the other SAS controller of node 2 to
the In-1 port of RAID controller 1 in the MD3000 RAID enclosure.
