What is pdReadAhead?
This turns the physical drive's read-ahead feature on(1) or off(2). An admin tunes this for workload: enabling it can help sequential-read-heavy workloads, while disabling it may suit purely random-access workloads.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.674.3.2.3.2.1.14 snmpwalk -v2c -c public <target> LSIRAID-IDE-MIB::pdReadAhead
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.674.3.2.3.2.1.14.1 snmpget -v2c -c public <target> LSIRAID-IDE-MIB::pdReadAhead.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.674.3.2.3.2.1.14.1 i <value>
