FCIO_RESET_LINK Error Message Occurs After Issuing the luxadm -e forcelip Command

Bug 15632822

Issue:

You might encounter this error message after issuing the luxadm -e forcelip command from a system with the following configuration:

• Oracle Solaris 10 10/09 OS running

• Adapter installed and connected to a Brocade 8000 FCoE switch

• Brocade 8000 FCoE switch connected to a tape zone on a FC SAN with an SL48-LTO4 FC tape library

If you issue the luxadm -e forcelip command upon the removal of a device from the tape zone, this message might be generated:

Error: FCIO_RESET_LINK ioctl failed.
Could not reset the loop

Workaround:

To avoid encountering the error message, manually unconfigure the unusable device (the device removed from the tape zone) at the attachment point of the device:

To Manually Unconfigure the Unusable Device

1. Issue the cfgadm -al unusable-device-attachment-point command to list the unusable device, as described in the following procedure.

   In this example, the attachment point of the unusable device is c1.

   > cfgadm -al c1
   Ap_Id                          Type         Receptacle   Occupant 
   Condition
   c1                             fc-fabric    connected    configured 
   unknown
   c1::12340080e512b600           disk         connected    configured 
   unknown
   c1::123400a0b82804a6           disk         connected    configured 
   unusable
   c1::123410a0008beb2a           tape         connected    configured 
   unknown
   >
   

2. Issue the cfgadm -c unconfigure -o unusable_SCSI_LUN unusable-device-attachment-point command to unconfigure the unusable devices on the attachment point.

   > cfgadm -c unconfigure -o unusable_SCSI_LUN c1

   Note - If a device is manually unconfigured, it must then be manually configured in order to return to the tape zone.
