DISKLIB-CHAIN : "/vmfs/volumes/Aida DB/icg4aida/temp.vmdk" : failed to open (Input/output error).
DISKLIB-LIB : Failed to open '/vmfs/volumes/Aida DB/icg4aida/temp.vmdk' with flags 0xe Input/output error (327689).

AIOMGR-U : stat o=1 r=0 w=0 i=0 br=0 bw=0
AIOMGR-S : stat o=1 r=3 w=0 i=0 br=49152 bw=0
