HBA data traffic monitor in Solaris 10.
Hi All
We have T4-4 Server with 2 HBA configured for SAN connectivity. We want to monitor Data traffice going through these HBA. On other AIX system we have that capability with nmon. Following screen shows nmon HBA monitoring can we achieve same in Solaris 10.

tran_setcap

tran_getcap(9E) 						Driver Entry Points						   tran_getcap(9E)

NAME

       tran_getcap, tran_setcap - get/set SCSI transport capability

SYNOPSIS

       #include <sys/scsi/scsi.h>

       int prefixtran_getcap(struct scsi_address *ap, char *cap, int whom);

       int prefixtran_setcap(struct scsi_address *ap, char *cap, int value, int whom);

INTERFACE LEVEL

       Solaris architecture specific (Solaris DDI).

PARAMETERS

       ap	Pointer to the scsi_address(9S) structure.

       cap	Pointer to the string capability identifier.

       value	Defines the new state of the capability.

       whom	Specifies whether all targets or only the specified target is affected.

DESCRIPTION

       The  tran_getcap()  and	tran_setcap() vectors in the scsi_hba_tran(9S) structure must be initialized during the HBA driver's attach(9E) to
       point to HBA entry points to be called when a target driver calls scsi_ifgetcap(9F) and scsi_ifsetcap(9F).

       tran_getcap() is called to get the current value of a capability specific to features provided by the HBA hardware or driver.  The name	of
       the capability cap is the NULL terminated capability string.

       If  whom  is  non-zero,	the  request  is for the current value of the capability defined for the target specified by the  scsi_address(9S)
       structure pointed to by ap; if whom is 0, all targets are affected; else, the target specified by the scsi_address structure pointed to	by
       ap is affected.

       tran_setcap() is called to set the value of the capability cap to the value of value. If whom is non-zero, the capability should be set for
       the target specified by the scsi_address(9S) structure pointed to by ap; if whom is 0, all targets are affected; else, the target specified
       by  the scsi_address structure pointed to by ap is affected. It is recommended that HBA drivers do not support setting capabilities for all
       targets, that is, whom is 0.

       A device may support only a subset of the defined capabilities.

       Refer to scsi_ifgetcap(9F) for the list of defined capabilities.

       HBA drivers should use scsi_hba_lookup_capstr(9F) to match cap against the canonical capability strings.

RETURN VALUES

       tran_setcap() must return  1 if the capability was successfully set to the new value, 0 if the HBA  driver does not  support  changing  the
       capability, and	-1 if the capability was not defined.

       tran_getcap() must return the current value of a capability or  -1 if the capability was not defined.
