I am unable to specify my own tag name. How can I change the tag name to one of my interest.

I need to create 3 partitions as told below

partitions:

/earth
/mars
/work

/earth and /work should be roughly equal in size, /mars should be twice the size of the others, if that is possible. If not 3 partitions of equal size will do.

Please, help me .

Thank you.

as far as i can see, you are doing wrong what can be done wrong...

  1. you used a disk out of a zpool
  2. you modiefied the partition table of a zpool disk
  3. you don't know the difference between partition tag and mount point (if i understand you right?)

what you should do:

  1. take some basic solaris trainings
  2. read the fine manuals provided at docs.sun.com (ZFS)
  3. create your filesystems with "zfs create ..." and use them instantly

You don�t have to change the tag just create the partition of required size , remember the slice number then label the disk and quit.

Create the mount point I mean create a three directory with in / or where ever you want e.g mkdir /earth etc

After that mount the slice into mount point ( /earth etc) like below

# mount /dev/dsk/c0t0d0s<slice number> /earth.

Place the entry in /etc/vfstab for reboot persistence
