Description: This object identifies the state of read cache.
What is hh3cDiskReadCache?
hh3cDiskReadCache controls whether read caching is enabled for a given disk. An admin toggles it to balance read performance against cache-related risk or resource usage, typically leaving it enabled by default to speed up repeated read operations. For example, an admin troubleshooting inconsistent read performance might check hh3cDiskReadCache to confirm caching wasn't inadvertently disabled on that disk.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.25506.10.3.1.1.1.12 snmpwalk -v2c -c public <target> HH3C-DISK-MIB::hh3cDiskReadCache
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.25506.10.3.1.1.1.12.1 snmpget -v2c -c public <target> HH3C-DISK-MIB::hh3cDiskReadCache.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.25506.10.3.1.1.1.12.1 s <value>
