[SunHELP] Veritas Volume Manager Question

[Tom Jones]

Issue the command vxprint -Aht, and redirect the output to a temp file.
Each volume that is mirrored will consist of two (or more) plexes.

Here a sample output from one of my servers:
v  arkhires_data1 fsgen      ENABLED  ACTIVE   4194304  SELECT    -
pl arkhires_data1-01 arkhires_data1 ENABLED ACTIVE 4206566 STRIPE 8/32     RW

sd c8t3d0-01    arkhires_data1-02 c8t3d0 0     525798   3/0       c8t3d0   ENA
sd c8t8d0-01    arkhires_data1-02 c8t8d0 0     525798   4/0       c8t8d0   ENA
sd c8t9d0-01    arkhires_data1-02 c8t9d0 0     525798   5/0       c8t9d0   ENA
sd c8t10d0-01   arkhires_data1-02 c8t10d0 0    525798   6/0       c8t10d0  ENA
sd c8t11d0-01   arkhires_data1-02 c8t11d0 0    525798   7/0       c8t11d0  ENA

The first line (starting with a v) identifies the volume arkhires_data1,
with a status and size. The second line, starting with pl, identifies a plex (consider
it a disksuite submirror when two plexes are defined for a volume).  The sd lines
identify the subdisks (disksuite metadevices).  In the above example, we are
striping across 8 disks and you can tell that we are mirroring across two separate
SCSI controllers (c7 and c8).  Note that the sizes are in 512 byte blocks, so this
is a 2GB volume, based on the size in the v record (4194304).

Try a man on vxprint for more details.  Another good command is vxstat which will
give you some idea of performance info for all volumes.
