This patch fixes problems that can be seen by the failure of importing disk groups on large clusters and while using LSM with SWXCR disks. 


A symptom of the import failure with large clusters
will be messages such as the following seen in the messages file:

   Jan 7 13:13:29 node1 vmunix: clsm_propose_ioctl: ioctl '152' failed 
   Jan 7 13:13:29 node1 vmunix: CLSM: vol_klog_setlog distribution
error. 
   Jan 7 13:13:29 node1 vmunix: clsm_propose: collision! proposal
already
   active. 
   Jan 7 13:13:29 node1 vmunix: clsm_propose: collision! proposal
already active. 
   Jan 7 13:13:29 node1 vmunix: clsm_propose_ioctl: ioctl '124' failed 
   Jan 7 13:13:29 node1 vmunix: clsm: vol_change_disk distribution
error.

A symptom of the problem of using disks (LUNs) on a SWXCR controller can
be seen by the following:

   # voldisksetup -i dsk0e
   lsm:voldisk: ERROR: Device dsk0e: define failed:
                Disk write failure

A symptom of the problem of using a KZPAC/SWXCR disks on boot:

 starting LSM in boot mode
 volio: Illegal vminor encountered
 lsm:vold: ERROR: enable failed: 
     Error in disk group configuration copies
     Disk group has no valid configuration copies; 
     transactions are disabled.
