What is sysReadAhead?
Read-ahead setting of the array's cache, writable; enabling it can speed up sequential reads. The source DESCRIPTION is only the generic placeholder text, so this reading is inferred from the object name and table position.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.19.1.2.1.6 snmpwalk -v2c -c public <target> T300-MIB2::sysReadAhead
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.42.2.12.2.2.19.1.2.1.6.1 snmpget -v2c -c public <target> T300-MIB2::sysReadAhead.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.42.2.12.2.2.19.1.2.1.6.1 s <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> sysReadAhead.1
