translate block device name to raw device name

[shai kedem]

Hello,

from most unix commands, you get the disk name by its block device name, i.e. /dev/dsk/c1t1d1
Does any one know how to get the raw device name (i.e. /dev/rdsk/c1t1d1) from the block device name ? is simply just putting "r" in front of the dsk word ? or is there a command in unix or a C function call which convert the names ?

Hi:

Yes, putting an 'r' in front of the block device name denotes the "raw" device name.

Hi ,
putting r in front of dsk is the option , but even from ioscan -fknC disk command it will show you device filenames , including raw device files.

Hi,

You're right, the only difference between the name of the block device and the name of the raw device is the 'r'.

If you want to convert it in a script, you can use:
RAW_DEVICE_NAME=`echo $BLOCK_DEVICE_NAME | sed 's/dsk/rdsk/'`
