I ran naviseccli -h IP cachecard -list on my CX4-960 system, but got error says:
C:\>naviseccli -h <IP> cachecard -list
Error: cachecard command failed
This storage system does not support any operation on cache memory card.
Looks like cx4960 doesn't suppot this hardware. What is cachecard?
Solved! Go to Solution.
Cache Card or Cache Module.is nothing but the Battery Backed Cache Module in AX100 & Ax150.
The AX150 houses a 256 MB Battery Backed Cache Module (BBCM) is socket attached to the Storage Processor.
It is used to protect the data that has not yet been committed to a disk surface, in the event of a hardware failure. This represents a mirror image of the write cache on the Storage Processor card. It has 2 lithium ion batteries with a 72 hour time limit and a 3 to 5 hour recharge time. It is equipped with three (3) LEDs, which are visible through the Storage Processor air dam. The Blue LED (left-most) indicates that data is stored in cache when the LED is illuminated. The Amber LED (center) indicates a fault condition. The Green LED (right-most) indicates fully charged batteries when illuminated solidly, and charging batteries when blinking. A graceful power down de-stages the cache data to the vault drives, so the BBCM is not needed and the batteries are not discharged.
You mentioned, the command is not working on CX4-960, Want to know why? Refer NaviCLI Admin Guide - Page Number 641. You'll see N/A for all the Series as this component is in AX100 & AX150 only.
