Question
The storage administrator is adding several disks to a pool of ASM disks. The current ASM_DISKSTRING parameter is "/dev/sda*", "/dev/sdb*", "/dev/sd*6". There are several hundred disk partitions currently. The new disks are /dev/sdf1, /dev/sdg1, /dev/sdh1, and /dev/sdd6. Which ASM_DISKSTRING parameter would perform the best by searching the fewest number of devices for ASM discovery?
Options
- AASM_DISKSTRING="/dev/sda*", "/dev/sdb*", "/dev/sd6","/dev/sd1"
- BASM_DISKSTRING="/dev/sda*", "/dev/sdb*", "/dev/sd6","/dev/sd"
- CASM_DISRSTRING="/dev/sd*"
- DASM_DISKSTRING=""
- EASM_DISKSTRING="/dev/sda*", "/dev/sdb*", "/dev/sd*6", "/dev/sdf1", "/dev/sdg1", "/dev/sdh1"

Explanation
Improving Disk Discovery Time The value for the ASM_DISKSTRING initialization parameter is an operating system璬ependent value that Oracle ASM uses to limit the set of paths that the discovery process uses to search for disks. When a new disk is added to a disk group, each Oracle ASM instance that has the disk group mounted must be able to discover the new disk using its ASM_DISKSTRING.
