seems that ASM file header is damaged try to use kfed repair 2012/8/3 De DBA <dedba@xxxxxxxxxx> > G'day, > > Yesterday the Unix sysadm rebooted a Sun M5000 on which I am running a > Solaris11 zone with Oracle 11.2.0.3 installed in it. ASM has 2 disk > groups, each with 2 disks. Before the reboot we shutdown Oracle and the > zone cleanly, and no errors are logged. > > After the reboot, ASM can no longer locate two out of 4 partitions, both > belonging to diskgroup DATA. The difference between the two that are no > longer "discovered" and the two other ones is that they are presented as > RAW by the Hitachi SAN, whereas the good ones (diskgroup REDO) are > presented as "Solaris". > > I have ascertained that all LUNs are still visible and accessible to > Solaris, and there is no error on the SAN.
