luxadm probe
All those commands failed to remove the path. The drive stills shows up as <drive... (13 Replies)

fcinfo - Fibre Channel HBA Port Command Line Interface SYNOPSIS
fcinfo hba-port [-l] [HBA_port_WWN...] fcinfo remote-port [-ls] [-p HBA_port_WWN] [REMOTE_port_WWN...] fcinfo [-V] fcinfo [-?] fcinfo is a command line interface that collects administrative information on fibre channel host bus adapter (HBA) ports on a host. It also collects data on any fibre channel targets that may be connected to those ports in a Storage Area Network (SAN). SUBCOMMANDS The following subcommands are supported: hba-port Lists information for the HBA port referenced by the specified HBA_port_WWN. If HBA_port_WWN is not specified, all fibre channel HBA ports on the host will be listed. remote-port Lists the remote-port information for those remote ports that are specified. If no REMOTE_port_WWN is specified, all remote ports that are visible through HBA_port_WWN are listed. OPTIONS
The following options are supported: -l, --linkstat Lists the link error statistics information for the port referenced by the specified HBA_port_WWN or REMOTE_port_WWN. -p HBA_port_WWN, --port HBA_port_WWN Retrieve remote port information from the HBA_port_WWN of the local HBA port on the host. The -p option can only be used with the remote-port subcommand and is a mandatory option. -s, --scsi-target Lists the SCSI target information for all remote ports the user has asked for. The -p, --port option must always be specified and must be a valid HBA port on the host. This HBA port will be used as the initiator for which to retrieve the SCSI level target information. Note that this will only function on remote port fibre channel World-Wide Names that support an FC4 type of SCSI. -V, --version Prints the version information. -?, --help Prints the usage information. EXAMPLES
Example 1: Listing all HBA ports The following command lists all fibre channel HBA ports on the host: # fcinfo hba-port HBA Port WWN: 210000e08b074cb5 OS Device Name: /dev/cfg/c1 Manufacturer: QLogic Corp.
