How to Change a Mirror's Options (Command Line)

After checking the prerequisites listed ("Prerequisites for Changing DiskSuite Objects"), and the preliminary information ("Preliminary Information for Changing Mirror Options"), use the metaparam(1M) command to display and change a mirror's options. Refer to Table 4-2 for a description of mirror options. For more information, refer to the metaparam(1M) man page.

# metaparam -r geometric d30
# metaparam d30
d30: mirror current parameters are:
