[Solved] Virtualizing the Fiber card (VFC) on P595
Hi,

We have a P595 machine with a dual port Fiber card per VIOs.

We have two VIOs in the box.

VIO1: ---> 2 port Fiber Card
VIO2: ---> 2 port Fiber Card

One port on each fiber card is utilized. Connected to SAN switches. We are getting all disks from SAN both for VIOs and LPARs.

Now we have connected our tape library to our SAN switches and from switches to our P595 box Fiber cards. We need to Virtualize the Fiber card in order to take backups.

----> Now if we Virtualize the fiber card then wouldnt it disturb the Fiber card on the machines? The disks comming from SAN would no longer be available. I found this link to do this:

Well folks this is how its going to work.

If one port is free we can utilize it and no need to worry about the other port as the vfc that would be created would be mapped "manually" to the available fcs

csx_releaseconfiguration

csx_ReleaseConfiguration(9F)				   Kernel Functions for Drivers 			      csx_ReleaseConfiguration(9F)

NAME

       csx_ReleaseConfiguration - release PC Card and socket configuration

SYNOPSIS

       #include <sys/pccard.h>

       int32_t csx_ReleaseConfiguration(client_handle_t ch, release_config_t *rc);

INTERFACE LEVEL

       Solaris DDI Specific (Solaris DDI)

PARAMETERS

       ch	Client handle returned from csx_RegisterClient(9F).

       rc	Pointer to a release_config_t structure.

DESCRIPTION

       This  function returns a PC Card and socket to a simple memory only interface and sets the card to configuration zero by writing a 0 to the
       PC card's COR (Configuration Option Register).

       Card Services may remove power from the socket if no clients have indicated their usage of the socket by  an  active  csx_RequestConfigura-
       tion(9F) or csx_RequestWindow(9F).

       Card Services is prohibited from resetting the PC Card and is not required to cycle power through zero(0) volts.

       After  calling  csx_ReleaseConfiguration()  any	resources  requested  via  the request functions csx_RequestIO(9F), csx_RequestIRQ(9F), or
       csx_RequestWindow(9F) that are no longer needed should be returned to Card Services via	the  corresponding  csx_ReleaseIO(9F),	csx_Relea-
       seIRQ(9F),  or csx_ReleaseWindow(9F) functions. csx_ReleaseConfiguration() must be called to release the current card and socket configura-
       tion before releasing any resources requested by the driver via the request functions named above.

STRUCTURE MEMBERS

       The structure members of release_config_t are:

       uint32_t     Socket;	/* socket number */

       The Socket field is not used in Solaris, but for portability with other Card Services implementations, it should  be  set  to  the  logical
       socket number.

RETURN VALUES

       CS_SUCCESS

	   Successful operation.

       CS_BAD_HANDLE

	   Client handle is invalid or csx_RequestConfiguration(9F) not done.

       CS_BAD_SOCKET

	   Error getting or setting socket hardware parameters.

       CS_NO_CARD

	   No PC card in socket.

       CS_UNSUPPORTED_FUNCTION

	   No PCMCIA hardware installed.

CONTEXT

       This function may be called from user or kernel context.
