    This looks like a DNS issue. check /etc/netsvc.conf and /etc/resolv.conf file on the RS/6000. You should have the dns server listed on /etc/resolv.conf and in /etc/netsvc.conf you need hosts=bind,local or hosts=local,bind.

    Loading 5.1 on F-80 "kmod_load" Error

    Hi John, It is a microcode problem on the CDROM drive and it has to be updated. Contact IBM Hardware or follow this URL http://www.rs6000.ibm.com/support/micro/40xcdrom.html#ToC_3 and http://www.rs6000.ibm.com/support/micro/download.html

    Loading 5.1 on F-80 "kmod_load" Error

    Not installed 5.1 on F80. But heard that in some recent IBM RS/6000 the CDROM drive is IDE instead of SCSI. So you need a particular set of AIX5.1 CD which contains driver for IDE.

But when you add more disks to the volume group you may not be able to extend your filesystem if it does not satisfy the stripe width.

    Attention light is lit on p610, what causes it?

    You have to shutdown the machine.When it comes up next time and the Rs/6000 logo is displayed press F1 or just 1 according to your console type. Then go to SMS menu.Then clear the errorlog from there. It will definitely fix the problem. This is nothing but clearing the NVRAM
