Solaris OS is not sending Process Login (PRLI) data to the tape device during a path recovery sequence.
No error message is displayed to the user, but the problem can be identified from:
Regular system log messages indicates a path issue, such as offline or online.
Cfgadm -al command. This command shows the failed condition for the tape device.
I/O to a tape device has ceased.
Workaround:
To recover from this situation, use the luxadm forcelip command to the FC host bus adapter. For example:
luxadm -e forcelip /dev/cfg/c99
c99 is the specific controller that is being used to communicate with the tape transport.
