Couldn't find driver matching arguments

[BAUKnight]

salam,
i am facing a problem with oracle RAC installation, i am now stuck in creating a virtual device file for the database disks,

disk 10 0/3/2/0.1.0.0.0.1.0 sdisk CLAIMED DEVICE HP HSV200
/dev/dsk/c6t1d0 /dev/rdsk/c6t1d0 /dev/rdsk/db_database

While on dbclust1, the db_database has the following device files (dsk / rdsk) c2t1d0

disk 27 0/3/1/0.1.0.0.0.1.0 sdisk CLAIMED DEVICE HP HSV200
/dev/dsk/c2t1d0 /dev/rdsk/c2t1d0 /dev/rdsk/db_database



Based on oracle installation manual, “Please note that the device paths for Oracle Clusterware and ASM disk must be the same from both systems. If they are not the sam, use the following command to map them to new virtual device name:

#mksf –C disk –H -I 62
#mksf –C disk –H -I 62 –r

Now, dbclust2 has a device file name (/dev/dsk/c2t1d0) which points to the internal HDD, so we cannot map this device file on dbclust2, while dbclust1 does not have a device file name /dev/dsk/c6t1d0  we must create a virtual device file called /dev/dsk/c6t1d0 on dbclust1 and map it to the same HW path of db_database file on dbclust1. Here are the commands we shall use and the result of executing them

root@dbclust1:/>mksf -C disk -H 0/3/1/0.1.0.0.0.1.0 -I 62 /dev/dsk/c6t1d0
mksf: Couldn't find driver matching arguments


can anyone help regarding this error.
thx in advance
