Updating ssd.conf configuration file (Solaris 10 and 11.0-11.3 SPARC)
About this task
The ssd.conf host file is used to control options for SCSI disk storage device.
Steps
1.
Run the following command to verify the ssd.conf file location:
# ls /etc/driver/drv/
2.
If the file is not in the expected location, run the following command to copy it from
/kernel/drv
:
# cp /kernel/drv/sd.conf /etc/driver/drv
3.
Run the following commands to create a backup copy and modify the file:
# cp -p /etc/driver/drv/sd.conf /etc/driver/drv/sd.conf_ORIG
# vi /etc/driver/drv/sd.conf
Example
Below are the entries that are recommended for PowerStore storage.
