Can you show the output of vxdctl list?  I haven't touched HPUX in a long time.

If I understan your question correctry, then yes, you can.

vxdctl hostid newhostid

And that's all

Hi all,

first I would like to thank you for your answers and will try to reply to them at once.

Darren, below is output from “vxdctl list” from both systems:

systema:/root # vxdctl list

Volboot file

version: 3/1

seqno:   0.3

cluster protocol version: 70

hostid:  systema

hostguid:  {2eb2f636-1dd2-11b2-a5de-37cb1f1e2cad}

systemb:/root # vxdctl list

Volboot file

version: 3/1

seqno:   0.3

cluster protocol version: 70

hostid:  systemb

hostguid:  {2eb2f636-1dd2-11b2-a5de-37cb1f1e2cad}

Anthony, I assume that “vxdctl hostid” changes just hostid not hostguid and I hope we tried it in test and it didn’t passed.

In production we used “vxdctl init” and it changed only hostid not hostguid as well. Its function seems to be same as in VxVM 4.1.

Hello.
Yes, you are right, vxdctl hostid change hostidnly. hostguid is generated by
/etc/vx/uuid/bin/osuuid command and you can look at it by :
/etc/vx/uuid/bin/osuuid list
also it is written to /etc/.osuuid  and /etc/vx/volboot file.
So you can change osuuid by removing
/etc/.osuuid
/etc/vx/uuid/bin/osuuid create --reset
then stop vxconfigd
rm /etc/vx/volboot
vxdctl init
vxdctl enable

I'm not sure that this is "supported" way but it works.
