Installing Storage Arrays
If you are installing new host adapters in your nodes, shut down and power off Node A.
6
For the procedure about how to shut down and power off a node, see your Oracle Solaris
Cluster system administration documentation. For a list of Oracle Solaris Cluster
documentation, see
Install the host adapters in Node A.
7
For the procedure about how to install host adapters, see the documentation that shipped with
your host adapters and nodes.
Cable the storage array or storage system to Node A.

For cabling diagrams, see
Ensure that each device in the SCSI chain has a unique SCSI address.
9
To avoid SCSI-chain conflicts, the following steps instruct you to reserve SCSI address 7 for one
host adapter in the SCSI chain and change the other host adapter's global scsi-initiator-id
to an available SCSI address. Then the steps instruct you to change the scsi-initiator-id for
local devices back to 7.
Note –
scsi-initiator-id to a SCSI address for that disk slot. This precaution minimizes future
complications if you install additional disk drives.
a. If necessary, power on the storage devices.
Note –
tasks at the ok prompt.
For the procedure about powering on a storage device, see the service manual that shipped
with your storage device.
b. If necessary, power on a node, but do not allow it to boot. If necessary, halt the system to
continue with OBP Monitor tasks.
c. Set the scsi-initiator-id for one node to 6.
{1} ok setenv scsi-initiator-id 6
scsi-initiator-id = 6
d. Find the paths to the host adapters that connect to the local disk drives.
{0} ok show-disks
Use this information to change the SCSI addresses in the nvramrc script. Do not include the
/sd directories in the device paths.
