The permanent I/O error occurring on a direct access storage device (in the previous message) with channel unit address xxx may be due to a defective disk drive or pack.
The system continues operation. The SWAP request does not complete until the operator responds to the succeeding reply message.
The disk drive or pack may be defective. If so, moving the pack or installing a different pack on the same drive will propagate the damage. Do not physically move the pack until both the pack and the drive have been inspected. Damage is indicated by a strange noise prior to turning the drive off. Another indication of damage to the device is a brown powder (dust) on disk surfaces or within the pack enclosure. Visually inspect the disk surfaces before removing the pack from the drive.
If after SWAP, an additional permanent I/O error occurs, or if there are additional indications of problems, do not swap the pack again.
Contact hardware support if there is any indication of damage.
