If you are installing new host adapters in your nodes, shut down and power off
Node A
.
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
“Related Documentation” on page 6
Install the host adapters in
Node A
.
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
Appendix A, “Cabling Diagrams.”
Ensure that each device in the SCSI chain has a unique SCSI address.
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 –
A slot in the storage array might not be in use. However, do not set the
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 –
If necessary, halt the nodes so that you can perform OpenBoot PROM (OBP) Monitor
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.
