The Italian Oracle Dba Blogger: CRS-5005: IP Address: is already in use in the network

After a change in ASM process parameter i restared the crs stack.
Everything went fine... almost the following resource are offline

ora.srvtst01.vip
ora.LISTENER.lsnr
ora.srvtst01.LISTENER_SRVTST01.LSNR

when i tried start the ora.srvtst01.vip i got the following error

$ crsctl start res ora.srvtst01.vip

CRS-2672: Attempting to start 'ora.srvtst01.vip' on 'srvtst01'

CRS-5017: The resource action "ora.srvtst01.vip start" encountered the following error:

CRS-5005: IP Address: 10.110.140.173 is already in use in the network

CRS-2674: Start of 'ora.srvtst01.vip' on 'srvtst01' failed

CRS-2679: Attempting to clean 'ora.srvtst01.vip' on 'srvtst01'

CRS-2681: Clean of 'ora.srvtst01.vip' on 'srvtst01' succeeded

CRS-2632: There are no more servers to try to place resource 'ora.srvtst01.vip' on that would satisfy its placement policy

CRS-4000: Command Start failed, or completed with errors.

That is strange the vip ip address should not be in use off course

$ nslookup srvtst01

Server: 145.72.247.10

Address: 145.72.247.10#53

Name: srvtst01.italie.nl

Address: 10.110.140.73

root@oesv7040:CRS:/root

$ nslookup srvtst01-vip.italie.nl.

Server: 145.72.247.10

Address: 145.72.247.10#53

Name: srvtst01-vip.italie.nl

Address: 10.110.140.173

As you see the ip address for the host and vip are different. When a do a SSH whith the vip ip 10.110.140.173 i connect to the host srvtst01 what is good.When i look with ifconfig command i don't see the IP address of the vip.

$ ifconfig

As you see i'm missing the vip ip address. I only see the host ip address.
To correct this i've to make a network alias and adjust it to ETH0 as it shoud be.
