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.

So does that mean that mknod devices are not persistent?
Thanks

Major numbers are specific to the device type and shouldn't change on a reboot.
Minors are dynamically allocated to the devices and can change on reboot after
reconfigurations.

Just wondering, can major and minor number change when the storage is
reconfigured? 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.
Thanks!

Subject: Clusterware 11.2.0.2 - identifying devices
Hello all,
I've encountered a challenge installing 11.2.0.2 RAC on a NetApp FiberSan. 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 11.2.0.2 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.
Thanks,
Lou Avrami
