Check About RAID-1 Volume Options.
Make sure that you have root privilege and that you have a current backup of all data.
Use one of the following methods to change the RAID-1 options.
From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node. Choose the mirror. Then, choose Action⇒Properties. Follow the onscreen instructions. For more information, see the online help.
Use the metaparam command to display and change a mirror's options.
# metaparam [mirror options] mirror |
See About RAID-1 Volume Options for a description of mirror options. Also, see the metaparam(1M) man page.
# metaparam -r geometric d30 # metaparam d30 d30: mirror current parameters are: Pass: 1 Read option: geometric (-g) Write option: parallel (default) |
In this example, the -r option changes a mirror's read policy to geometric.
# metaparam -w serial d40 # metaparam d40 d40: mirror current parameters are: Pass: 1 Read option: roundrobin (default) Write option: serial (-S) |
In this example, the -w option changes a mirror's write policy to serial.
# metaparam -p 5 d50 # metaparam d50 d50: mirror current parameters are: Pass: 5 Read option: roundrobin (default) Write option: parallel (default) |
In this example, the -p option changes a mirror's pass number to 5.
