Veritas Storage Foundation is the storage software we use on the HA cluster, and database servers. It contains two main parts, VxFS (a filesystem), and VxVM (a volume manager).
Cheat sheet[edit]
- List existing disks and volumes:
 % vxprint -u
Disk group: int
TY NAME ASSOC KSTATE LENGTH
dg int int - -
^-- the diskgroup, a collection of related disks. Most systems only has one diskgroup.
dm int01 c0t1d0s2 - 956g
^-- a physical disk. "c0t1d0" is the Solaris name, while "int01" is what Vx calls it.
v sql fsgen ENABLED 800g
^-- A top-level volume.
pl sql-01 sql ENABLED 800g
sd int01-02 sql-01 ENABLED 156g
sd int01-03 sql-01 ENABLED 643g
^-- Volumes are built on top of a plex (pl), which can contain multiple subdisks (sd).
This volume has two subdisks, which probably means it was resized at some point in
the past.
v sql-innodb fsgen ENABLED 10g
pl sql-innodb-01 sql-innodb ENABLED 10g
sd int01-01 sql-innodb-01 ENABLED 10g
- Add 100G to the 'sql' volume. This will automatically resize the filesystem as well.
# /etc/vx/bin/vxresize sql +100g
- Create a new volume:
# vxassist make myvol 150g
- Create a filesystem on it:
# mkfs -Fvxfs /dev/vx/rdsk/int/myvol
- Mount it:
# mount /dev/vx/dsk/int/myvol /myvol
- Delete a volume:
# vxassist remove volume myvol
