Hi, I have a CPG with 8 SSD each 200GB. Each cage is filled with 2 SSDs. CPG is 3+1 HA mode. My problem is, that the overall capacity is about 400GB. What i see is, that 5 disks are assigned on PORT A as preferred path and only 3 disks are assigned in PORT B. I am unable to switch the preferred path with servicemag command. Please help Alex |

Hello Alex, Check how much "spare" space they consumed when they installed your SSD. I do protest vehemently the practice of forcing SSD spare space when you have perfectly good FC available for spares, especially in instances where very few SSD drives are installed. The used 4 spindles worth of SSD for spares on my system, and I continue to protest. This reminds me to open a new case on this subject to protest some more. |
