Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Caching mode flags BIT 0 : Write Back Status (RW) 0: Disabled, 1: Enabled. BIT 1 : Read Ahead Disable (RW) 0: Enabled, 1: Disabled. BIT 2 : Enable/Disable keeping LD/LV off-line after controller initialization if cached write data was lost (RW) 0: Disabled, 1: Enabled. BIT 3 -- BIT 7 : Reserved (Set to 0). BIT 8 : Cache Optimization Option (RW) 0: Small/Random I/Os, 1: Large/Sequential I/Os BIT 9 -- BIT 15 : Reserved (Set to 0). BIT 16 -- BIT 18 : Periodic Cache Sync Period (RW) For interpretation of values, reference 'Periodic Cache Sync Period Value Cross-Reference List'. BIT 19 -- BIT 21 : Cache Flush Initiation Threshold (RW) For interpretation of values, reference 'Cache Flush Initiation Threshold Valid Cross-Reference List'. BIT 22 -- BIT 25 : Cache Flush Termination Threshold (RW) For interpretation of values, reference 'Cache Flush Termination Threshold Valid Cross-Reference List'. BIT 26 -- BIT 31 : Reserved (Set to 0).
What is cacheModeFlags?
A read-only bitmask summarizing caching behavior: bit 0 shows write-back cache status, bit 1 shows whether read-ahead is disabled, and bits 16-25 encode the periodic cache-sync period and the cache flush initiation/termination thresholds. An admin reads this to confirm whether the array is currently caching writes (faster but riskier on power loss) or running write-through.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1714.1.1.2.1 snmpwalk -v2c -c public <target> IFT-SNMP-MIB::cacheModeFlags
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1714.1.1.2.1.1 snmpget -v2c -c public <target> IFT-SNMP-MIB::cacheModeFlags.1
