Erasing a Tape in an HP StorageWorks DAT 72 Tape Drive Generates an Error (5067923)

An I/O error occurs when you use the magnetic tape control utility to erase a tape in an HP StorageWorks DAT 72 tape drive. When you type mt -f /dev/rmt/x erase, the process continues up to the default timeout of three hours. Then the process stops and the following error message is displayed:

/dev/rmt/x erase 1 failed: I/O error

Workaround: To avoid the error, add the following entry in the kernel/drv/st.conf file:

tape-config-list= "HP C7438A", "HP DAT-72", "CFGHPDAT72";
CFGHPDAT72 = 2,0x34,0,0x18659,4,0x47,0x47,0x47,0x47,1,120,
420,3600,36000,3600,3600,17400;
