Editing an I/O device

Select one or more I/O devices in the I/O Device List dialog and click on the Edit... button. The Edit I/O Device(s) dialog appears; if you selected more than one device, any changes you make in this dialog will apply to all selected devices and the Serial Number and Volume serial fields will be disabled. Device serial numbers can be set for all devices in a unit by editing the unit.

Any changes to volume serials (VOLSERs) that you make with HCM cause an immediate update of the IODF. You can also edit the VOLSERs in stand-alone mode. See also VOLSER reconciliation.

Edit the information and click on OK.

Note:

You cannot edit a device to change the device number. If it is necessary to change a device number, you must delete the device and create a new one with the desired number.
If you want to change the device type of a device that is defined in a subchannel set other than 0, then the device type change will only be accepted if the target device type can also be defined in an alternative subchannel set.
