If you are doing it manually correct. You can script it using a high enough minor number as to not conflict with other devices of the same type. ________________________________ From: LS Cheng [mailto:exriscer@xxxxxxxxx] Sent: Monday, March 21, 2011 8:08 AM To: Amaral, Rui Cc: Freek.DHooge@xxxxxxxxx; avramil@xxxxxxxxxxxxxx; oracle-l@xxxxxxxxxxxxx Subject: Re: Clusterware 126.96.36.199 - identifying devices So does that mean that mknod devices are not persistent?

For example addking new disks or remove and readd? I am asking because mknod relies on minor and major numbers, would like to know if these number are persistent even after storage reconfiguration.

I thought I would run it by oracle-l and see if anyone might have a solution. I was doing an advanced installation of RAC 18.104.22.168 on a 2-node Solaris 10 configuration. This is for a data warehouse application for a vendor, with 80 TBs of storage for the database. I start the installer, input the SCAN address, set up the virtual IPs and SSH connectivity, then come to the "Create ASM Disk Group" screen. The top of the screen populates the name of the disk group as DATA, there are radio buttons for redundancy, then there is a box with all of the devices under /dev/rdsk, with checkboxes to the left. It looks like there are at least 6 screens of these devices. The list looks like this: Device Size MB - /dev/rdsk/c10t60A98000486E6476575A62584A594C66d0s2 2091473 - /dev/rdsk/c10t60A98000486E6476575A62584A612D76d0s2 2097152 .... I have a list of devices and what disk groups I want to assign them to ... but trying to pick device names out of a list of dozens like the ones above in an X-Windows screen is proving to be just about impossible. Any ideas would be greatly appreciated. Should I be looking at a response file? I've never used a response file for a Clusterware installation.
