chkdev - how to display the identification of disks and their capabilities in IBM VIO Server |
Description
As of Virtual I/O Server Fix Pack 22, a new command has been introduced to assist with the identification of disks and their capabilities. The Virtual I/O Server chkdev command is capable of displaying the IEEE, UDID, and PVID and provides some additional information:
#chkdev
NAME: hdisk0
IDENTIFIER: 2F1135000C50006D9C1F30BST9146802SS08IBM-ESXSsas
PHYS2VIRT_CAPABLE: YES
VIRT2NPIV_CAPABLE: NA
VIRT2PHYS_CAPABLE: NA
Where:
PHYS2VIRT_CAPABLE: This disk may be virtualized to a logical partition. Once this is performed, this field will change to a value of NA if the mapping is successful. A value of NO indicates this volume may not be virtualized.
VIRT2NPIV_CAPABLE: If the disk is capable of moving from a virtual SCSI environment to an N_Port ID Virtualization (NPIV) environment, this field will be set to YES, otherwise it will be set to NO. A value of NA means that this disk has already been moved and the Virtual Target Device or VTD as it is abbreviated in the command output, will indicate the mapping.
VIRT2PHYS_CAPABLE: If the device is capable of moving from a virtual environment to a physical environment and is currently mapped to a VTD then the value here will be YES. A value of NA means the disk is not in use by a VTD, while a value of NO means the disk is not capable of such a move. |
