Symptoms
Database storage is ASM on an HP-UX system.
A disk fails in an ASM diskgroup.
ASM does not recover and I/Os hang indefinitely.
All types of SQL statements requiring I/O can be affected.
Asynchronous I/O is enabled.
Solution
To implement the solution enable minor device number 4 for device /dev/async, i.e.
crw-rw-rw- 1 bin bin 101 0x000004 Sep 12 2006 /dev/async
Major and minor device numbers are assigned to a character device when the device is created with mknod. In order to change minor device number, /dev/async needs to be recreated.
$ /sbin/mknod /dev/async c 101 0x0
