Hi list,
I'm testing RAC + ASM + iSCSI-shared-storage on SUSE SLES10 SP1.
Configuration of RAC:
1. 2 nodes (a + b) with 2 instances TEST1 and TEST2
Configuration of ASM:
1. normal redundancy
2. Diskgroup data with 2 failure groups st01_data and st02_data.
Each failure group has 1 disk (/dev/raw/raw11 and /dev/raw/raw12)
raw11 is an iSCSI-Target from node st01.
raw12 is an iSCSI-Target from node st02.
3. Diskgroup reco (recovery area) with 2 failure groups st01_reco and
st02_reco.
Each failure group has 1 disk (/dev/raw/raw6 and /dev/raw/raw7)
raw6 is an iSCSI-Target from node st01.
raw7 is an iSCSI-Target from node st02.
Taking offline of the iSCSI-Target node st01 produce a strange error
within the database:
- no commit possible
- alter system switch logfile not possible
- database seems to be readonly
srvctl says: All RAC-Services and Instances are running.
alert.log of RAC-Instance TEST1:

<<<<<<<<<<<
Reconfiguration of ASM by " alter diskgroup add failgroup ..." (after
deleting the asm-metadata on the raw device)
takes no effect.
After restart of the RAC-instances all work fine !
Any hint ?
Regards
Klaus
