Hi,

actual architecture:
OS: AIX 5.3
RDBMS: 2 nodes RAC 10.2.0.4
ASM-CRS: 11.1.0.7
Storage Type: EMC Symmetrix
Disk Type: rawdevice
Disk Group: +DATA, +FRA

Extract of the V$ASM_DISK:
GROUP_NUMBER: 1 (+DATA)
DISK_NUMBER: 0
HEADER_STATUS: MEMBER
NAME: DATA_0000
PATH: /dev/rhdisk10 
lsattr -El hdisk10 | grep unique_id: 3521360060160E8742400918BA15EC6ADDE1106RAID 503DGCfcp

After the activity of the OS/Storage admin, the rawdevice /dev/rhdisk10 (unique_id: 3521360060160E8742400918BA15EC6ADDE1106RAID 503DGCfcp) 
change enumeration and could be /dev/rhdisk4 (but ever same unique_id: 3521360060160E8742400918BA15EC6ADDE1106RAID 503DGCfcp).
The content of the disk is not changed.
This is a problem for ASM or is trasparent ?

Howdy, Stranger!
