Solaris hard disk mirrored
 

Hi,

I wish to know the commands to check if the hard disks for Solaris was mirrored ?

hi, you should check the output from:
metastat for soft mirrors
raidctl for hardware mirroring

Post the output of df -k, metastat -p, and format.

there are actually two types of mirroring:
- hardware mirroring
- software mirroring

an example of hardware mirroring is that of sun fire v440. you can check out the command raidctl for this type.

for the software mirroring aka metadevices, you can check this out through a combination of commands:
- df
- metastat

with df, you check whether you are mounting a metadevice or a non-metadevice. metadevices are distinguised by /dev/md/dsk/dnn where nn is a number. using metastat dnn, you can determine what kind of metadevice you are looking at. when it says mirrored, then you are using software mirroring for solaris.
