The managehostconnect command modifies the volume group assignment for a SCSI host port.
>>-managehostconnect--+-------------------------+---------------> '- -dev--storage_image_ID-' >-- -volgrp--+-volume_group_ID-+--+-port_grp_number-+---------->< '-none------------' '-" - "---------'
Parameters
Notes:
- The managehostconnect command can be disruptive to host system I/O operations if the affected host port is logged onto the target storage unit. Ensure that the host port is offline to the host system before you process the managehostconnect command.
- This command is used more effectively after you have issued the lshostconnect or showhostconnect commands and have analyzed the reports that are generated by these commands. The information that is reported by these commands can help you ensure that you specify the correct port group number when you issue the managehostconnect command.
- -dev storage_image_ID
- (Optional) Specifies the storage image ID, which consists of the manufacturer, type, and serial number.
- -volgrp volume_group_ID | none
- (Required) Specifies that the SCSI host port connections that are associated with the specified port group number will be modified to access this volume group ID. A volume group ID is a four-digit decimal number with no leading zeroes, prefixed with the letter V.
- port_grp_number | -
- (Required) Specifies the SCSI host port group number that associates two or more host ports as having access to a common volume group.
