Solaris media boot network parameters issue
In a media boot of a Solaris client, the Solaris code polls the local subnet. The code polls to determine if any computer on the local subnet has a record of the network parameters for the booting client. If a JumpStart server has network parameters for the client in the /etc/ethers or /etc/bootparams file, those parameters are used for the boot process. The parameters are used even if they are different than the network parameters for the boot interface that are configured in BMR.
If network parameters for the client exist, the restore may fail.
To work around this issue, do one of the following:
Remove all references to the client system from the following files in all other computers in the subnet of the client:
/etc/ethers file /etc/bootparams
Unplug the booting client from the network until the media boot configures the network parameters for the restore.
