► The NIM server is properly configured as the NIM master, and the basic NIM resources
have been defined.
► The Fibre Channel Adapters are already installed in the machine onto which AIX is to be
installed.
► The Fibre Channel Adapters are connected to a SAN and, on the Storage Subsystem,
have the designated logical drive defined and mapped to the host or NIM client.
► The target machine (NIM client) currently has no operating system installed and is
configured to boot from the NIM server.
For more information about how to configure a NIM server, see NIM from A to Z in AIX 5L,
SG24-7296.
NIM installation procedure
Prior the installation, you can modify the bosinst.data file (for a more automated install),
where the installation control is stored. Insert your appropriate values at the following stanza:
SAN_DISKID
This stanza specifies the World Wide Port Name and a Logical Unit ID for Fibre Channel
attached disks. The World Wide Port Name and Logical Unit ID are each in the format
returned by the lsattr command, that is, “0x” followed by 1-16 hexadecimal digits. The
ww_name and lun_id are separated by two slashes (//):
SAN_DISKID =
Example 3-16 LUN ID example
SAN_DISKID = 0x0123456789FEDCBA//0x2000000000000
You can specify PVID (the example uses an internal disk):
target_disk_data:
PVID = 000c224a004a07fa
SAN_DISKID =
CONNECTION = scsi0//10,0
LOCATION = 10-60-00-10,0
SIZE_MB = 34715
HDISKNAME = hdisk0
To create a BOS installation client using the NIM, follow these steps:
1. Enter the command:
# smit nim_bosinst
2. Select the lpp_source resource for the BOS installation.
3. Select the SPOT resource for the BOS installation.
4. Select the BOSINST_DATA to use during installation option, and select a bosinst_data
resource that is capable of performing a unprompted BOS installation.
5. Select the RESOLV_CONF or define the host to use for network configuration option, and
select a resolv_conf resource.
6. Select the Accept New License Agreements option, and select Yes. Accept the default
values for the remaining menu options.
7. Press Enter to confirm and begin the NIM client installation.
