How to Increase the Number of Default Disksets (Command Line)

This task shows you how to increase the number of disksets from the default value of 4.

If you lower this number, any diskset existing between the old number and the new number may not be persistent.

1. After checking the prerequisites ("Prerequisites for Troubleshooting the System"), edit the /kernel/drv/md.conf file.

2. Change the value of the md_nsets field. Values are supported up to 32.

3. Save your changes.

4. Perform a reconfiguration reboot to build the metadevice names.

   # boot -r

Example -- md.conf File

Here is a sample md.conf file configured for five disksets. The value of md_nsets is six, which results in five disksets and one local diskset.
