For an overview of the status information associated with RAID-1 volumes and submirrors, see Understanding Submirror Status to Determine Maintenance Actions.
Use one of the following methods to the check mirror or submirror status.
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.
Run the metastat command on the mirror to view the status of each submirror.
# metastat mirror |
See How to Change RAID-1 Volume Options to change a mirror's pass number, read option, or write option.
See metastat(1M) for more information about checking device status.
Here is sample output from the metastat command. Use metastat command without a mirror name to display all the status of all mirrors.

Use the metastat command with a mirror name argument to display output for a specific mirror.
metastat d70 d70: Mirror Submirror 0: d71 State: Okay Pass: 1 Read option: roundrobin (default) Write option: parallel (default) Size: 12593637 blocks d71: Submirror of d70 State: Okay Size: 12593637 blocks Stripe 0: Device Start Block Dbase State Reloc Hot Spare c1t3d0s3 0 No Okay Yes Stripe 1: Device Start Block Dbase State Reloc Hot Spare c1t3d0s4 0 No Okay Yes Stripe 2: Device Start Block Dbase State Reloc Hot Spare c1t3d0s5 0 No Okay Yes |
For each submirror in the mirror, the metastat command shows the status, an “invoke” line if there is an error, the assigned hot spare pool (if any), the size in blocks, and information about each slice in the submirror.
