Hello, I'm having difficulties starting ASM on RAC. This was previously working, the nodes were rebooted, and is now failing. These are production databases, so any help is greatly appreciated: SQL> startup; ASM instance started Total System Global Area 75497472 bytes Fixed Size 777772 bytes Variable Size 74719700 bytes Database Buffers 0 bytes Redo Buffers 0 bytes ORA-15032: not all alterations performed ORA-15063: diskgroup "STK" lacks quorum of 2 PST disks; 0 found the alert log displays: NOTE: cache registered group STK number=1 incarn=0x8f081786 NOTE: cache dismounting group 1/0x8F081786 (STK) NOTE: dbwr not being msg'd to dismount ERROR: diskgroup STK was not mounted The disks are showing up properly in the OS (RHEL v3).
