UNCLASSIFIED Hi Neil,
There are 2 ways I can think of to achieve what you want: 1. delete /etc/vx/disk.info and run vxdctl enable (don't edit it, it's rebuilt at every boot). This will rebuild that file and set up all your vx devices. However, this is not a guarantee that the devices will be in order. The order will be whatever the OS has decided it is, based on discovery order. 2. To try and achieve physical device discovery is in order, the only way I can think of is to present each of the 29 disks to the cluster 1 at a time. And then run vxdctl enable after each disk discovery. However, this still won't guarantee in order device discovery, as the devices have already been discovered. You may need to do some funky commands with devfsadm -C and luxadm to really get rid of the physical devices. (Even cfgadm to remove the array entirely and start again). Hey - you've got a cluster - just reboot -- -r after removing the devices :-) Enabling enclosure based naming won't affect anything. It may change some existing disks names, but you will see it will be better. It will make it easier for you to identify which array is which.

The disks have been JBOD named by the look of it (Disk_0 to Disk_28) rather than enclosure named. I believe that this may be because I had an old version of the ASL installed. I've now updated this ASL. Additionally, whilst the Solaris device names seem to match on the two cluster nodes, the Disk_x names do not. This doesn't technically matter but since this is a cluster I was hoping to get both nodes to look the same for easier management. and disk identification. So....does anyone know the easiest way to wipe out the new VX disks (not the OS devices) so I can re-vxdctl enable and hope that the new ASL picks the enclosure up correctly (OR can I just try and apply enclosure based naming through vxddladm ??? and if so will this affect other, pre-existing disks?) AND if I manage that (or even if not!) is there an easy way to get the two sides to match ? It seems I can edit /etc/vx/disk.info but is that the only way? thanks, Neil _______________________________________________ Veritas-vx maillist - Veritas-vx@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-vx IMPORTANT: This email remains the property of the Department of Defence and is subject to the jurisdiction of section 70 of the Crimes Act 1914.
