ZFS Online Pool Expansion Does Not Work For Solaris Cluster 4.x Clustered Zpools

Symptoms
ZFS online pool expansion does not work on Solaris Cluster 4.x clustered pools
Issue clarification

Cause
System running Solaris 11.1 with zpool online expansion does not understand global name space in Solaris cluster
 Cause determination
Command use for online expansion of Sun Cluster LUNs
[root@cbneuh02b]$ truss -aefEl -vall -o truss.out -u libzfs zpool online -e
XTOHTXX1_db /dev/did/dsk/d63s0 /dev/did/dsk/d62s0 /dev/did/dsk/d61s0 /d>
: cannot relabel 'dsk/d63s0': unable to open device
: cannot relabel 'dsk/d62s0': unable to open device
: cannot relabel 'dsk/d61s0': unable to open device
: cannot relabel 'dsk/d60s0': unable to open device

From the truss data, it seems that libzfs is not able to filter the Solaris
Cluster device path and finally wrong pathname is passed into
zpool_relabel_disk().

Need to take an outage to export zpools, and re-import them in order to
expand ZFS pools.
