Check Background Information for Changing RAID 1 Volume Options.
Use one of the following methods to change mirror options.
From the Enhanced Storage tool within the Solaris Management Console, open the Volumes node, choose the mirror, then choose Action->Properties. Follow the instructions on screen. For more information, see the online help.
Use the metaparam command to display and change a mirror's options. For example, to change a mirror to “first”, rather than round-robin, for reading, use the following:
# metaparam -r first mirror |
See 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.
