Dear!
I've to install Oracle 10g on Solaris 10, Sparc. I prepared anything successfully, but, when I gone to create ASM instance, I found the Create new bow did not show any disks into. I take brief something:
1- Sparc & disks preparation:
# isainfo
sparcv9 sparc
# ls -lL /dev/rdsk/c4t50060E800570B715d0s6
crw-rw---- 1 root sys 336, 14 Sep 28 14:08 /dev/rdsk/c4t50060E800570B715d0s6
# ls -lL /dev/rdsk/c4t50060E800570B715d2s6
crw-r----- 1 root sys 336, 62 Sep 28 14:09 /dev/rdsk/c4t50060E800570B715d2s6
# ls -lL /dev/rdsk/c4t50060E800570B715d3s6
crw-r----- 1 root sys 336, 30 Sep 28 14:09 /dev/rdsk/c4t50060E800570B715d3s6
# ls -lL /dev/rdsk/c4t50060E800570B715d4s6
crw-r----- 1 root sys 336, 78 Sep 28 14:09 /dev/rdsk/c4t50060E800570B715d4s6
# ls -lL /dev/rdsk/c4t50060E800570B715d5s6
crw-r----- 1 root sys 336, 94 Sep 28 14:09 /dev/rdsk/c4t50060E800570B715d5s6
# ls -lL /dev/rdsk/c4t50060E800570B715d6s6
crw-r----- 1 root sys 336, 110 Sep 28 14:09 /dev/rdsk/c4t50060E800570B715d6s6
Those 6 partitions disks above were supplied to ASM, so, I make mknod to link them.
# ls -lrt /asmdisks
total 0
crw-r--r-- 1 oracle dba 336, 110 Sep 28 15:35 disk6
crw-r--r-- 1 oracle dba 336, 94 Sep 28 15:39 disk5
crw-r--r-- 1 oracle dba 336, 78 Sep 28 15:39 disk4
crw-r--r-- 1 oracle dba 336, 30 Sep 28 15:39 disk3
crw-r--r-- 1 oracle dba 336, 14 Sep 28 15:39 disk2
crw-r--r-- 1 oracle dba 336, 62 Sep 28 15:39 disk1
Well, I go to ASM, but
And nothing on Available Disk Groups.
May you guide me to do some thing now?
Thank you very much!

The Solaris disks has 2 links, 1 to /dev/rdsk, 1 to /devices/pseudo, and I had changed owner to oracle for 2 links
# chown oracle:oinstall /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:b,raw
# chmod 770 /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:b,raw
# chown oracle:oinstall /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:c,raw
# chmod 770 /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:c,raw
# chown oracle:oinstall /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:d,raw
# chmod 770 /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:d,raw
# chown oracle:oinstall /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:e,raw
# chmod 770 /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:e,raw
# chown oracle:oinstall /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:f,raw
# chmod 770 /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:f,raw
# chown oracle:oinstall /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:g,raw
# chmod 770 /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:g,raw
# chown oracle:oinstall /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:h,raw
# chmod 770 /devices/pseudo/dlmndrv@1/dlmfdrv@w50060e800570b715,0:h,raw
OKie, when I re-list, I found the owner was oracle (group oinstall) for 2 links. Back to ASM created box, I've found nothing on, so I make to decide clear ASM data with
dd if=/dev/zero of=/asmdisks/disk1 bs=8192 count=100
dd if=/dev/zero of=/asmdisks/disk2 bs=8192 count=100
dd if=/dev/zero of=/asmdisks/disk3 bs=8192 count=100
dd if=/dev/zero of=/asmdisks/disk4 bs=8192 count=100
dd if=/dev/zero of=/asmdisks/disk5 bs=8192 count=100
dd if=/dev/zero of=/asmdisks/disk6 bs=8192 count=100
And I re-ran ASM create instance, however, no-rawdevices was listed on.
May you clarify me?
Thank you!
