Hi,

I have hostname problem with tow nodes cluster, with each node's hostname set to 'nin1' and 'nin2', however after system reboot or HACMP service start operation each node's hostname is changed to 'nin1_nb' and 'nin2_nb'.

The hostname was set right, so I checked the odm:

nin2#odmget CuAt|grep -ip nin2_nb
CuAt:
name = "iscsi0"
attribute= "initiator_name"
value = "iqn.nin2_nb.hostid.00000000"
type = "R"
generic = "DU"
rep = "s"
nls_index = 3

So my questions are:

1. what the hell is 'iscsi0' doing for? why system set hostname according to 'iscsi0's initiator_name value? and why cluster service start operation could cause hostname change?

2. how to correct it?

Thanks in advance.

What command are you using to check the hostname?

Problem resolved, thanks for asking.

It turns out to have nothing to do with the device 'iscsi0' but a set hostname command in file /etc/rc.net:

hostname nin2_nb

that's why start cluster service would change the hostname too.

Thanks again
