VERITAS VOLUME MANAGER :SUBDISK OPERATIONS

SUB-DISK OPERATIONS:-
1)TO CREATE SUBDISK
-bash-4.1# vxmake -g test sd sd1 d0,0,100m
-bash-4.1# vxprint -svt
Disk group: test
V  NAME         RVG/VSET/CO  KSTATE   STATE    LENGTH   READPOL   PREFPLEX UTYPE

SV NAME         PLEX         VOLNAME  NVOLLAYR LENGTH   [COL/]OFF AM/NM    MODE
SC NAME         PLEX         CACHE    DISKOFFS LENGTH   [COL/]OFF DEVICE   MODE

sd sd4          -            d3       0        204800   -         c2d15    ENA
2) TO JOIN SUBDISK
==>> SUB DISK MUST BE OCCUPIE CONTINUE BLOCKS
==>> TO JOIN SUB DISK BLOCKS SHOUD BE CONTINOUS (EX: SDX=1-100BLK , SDY=101-200BLK THEN ONLY POSSIBLE) IF NOT JOING IS NOT POSSIBLE.
==>> BETWEEN TWO  DISK THRERE IS NO JOINING OF SUBDISKS.
