|  |     Steve,
    
    I can reproduce this problem on my cluster. Only ShadowSet device seems
    to be affected by this problem.
    
    
A VMScluster with a VAXstation 4000-96, an Alpha Server 2100 4/200 and
an DEC3000-600, all systems running OpenVMS V7.1 with the following patches:
For AXP system
ALPCPU1601_071
ALPCPUC02_071
ALPMOUN01_071
ALPSHAD01_071
For VAX system
VAXACRT01_071
VAXMOUN01_071
VAXSHAD01_071
this problem can be reproduced easly!!!!!!!!!

Every things works as expected without the patch ALPMOUN01_071
