calculating the size of the luns using script
Hi
This is the lspv output of my server :
cbspsdb01 [/] #lspv
hdisk0 00c7518d2d512fd4 cdgvg active
hdisk1 00c7518d2dcbc9d6 cdgvg active
hdisk2 00c7518dcda9199a appvg active
hdisk3 00c7518dcda9388c itcamvg active
hdisk4 00c7518d85724ca6 rootvg active
Can anyone help me to write a script which will sum the size of all the hdisks and give the value ?
The script should give the sum value of (bootinfo -s hdisk0 + bootinfo -s hdisk1 + bootinfo -s hdisk2 + bootinfo -s hdisk3 + bootinfo -s hdisk4) in GigaBytes ?

pvmfsetsbuf
SETSBUF(3PVM) PVM Version 3.4 SETSBUF(3PVM)
NAME
pvm_setsbuf - Switches the active send buffer.
SYNOPSIS
C int oldbuf = pvm_setsbuf( int bufid )
Fortran call pvmfsetsbuf( bufid, oldbuf )
PARAMETERS
bufid Integer the message buffer identifier for the new active send buffer. A value of 0 indicates the default receive buffer.
oldbuf Integer returning the message buffer identifier for the previous active send buffer.
DESCRIPTION
The routine pvm_setsbuf switches the active send buffer to bufid and saves the previous active send buffer oldbuf. If bufid is set to 0
then the present active send buffer is saved and no active send buffer exists.
The routine is required when managing multiple message buffers. For example switching back and forth between two buffers. One buffer
could be used to send information to a graphical interface while a second buffer could be used send data to other tasks in the application.
EXAMPLES
C:
sbuf1 = pvm_setsbuf( sbuf2 );
Fortran:
CALL PVMFSETSBUF( NEWBUF, OLDBUF )
ERRORS
These error conditions can be returned by pvm_setsbuf
PvmBadParam
giving an invalid bufid.
PvmNoSuchBuf
switching to a non-existent message buffer.
