하드디스크 용량 확인 질문

솔라리스에서 하드디스크 개수와 용량을 확인하고 싶어 아래와 같이 검색해 보았습니다.   `format` 명령으로 확인한 내용 입니다.          0. c1t0d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>           <A>/pci@9,600000/SUNW,qlc@2/fp@0,0/ssd@w500000e0106a13e1,0</A>        1. c1t1d0 <FUJITSU-MAP3735FSUN72G-1201 cyl 14087 alt 2 hd 24 sec 424>           <A>/pci@9,600000/SUNW,qlc@2/fp@0,0/ssd@w500000e0106a4761,0</A>          2. c2t0d16 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@2/sd@0,10</A>        3. c2t0d17 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@2/sd@0,11</A>        4. c2t0d18 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@2/sd@0,12</A>        5. c2t0d19 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@2/sd@0,13</A>        6. c2t0d20 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@2/sd@0,14</A>        7. c2t0d21 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@2/sd@0,15</A>        8. c2t0d22 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@2/sd@0,16</A>          9. c3t0d16 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@1/sd@0,10</A>       10. c3t0d17 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@1/sd@0,11</A>       11. c3t0d18 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@1/sd@0,12</A>       12. c3t0d19 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@1/sd@0,13</A>       13. c3t0d20 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@1/sd@0,14</A>       14. c3t0d21 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@1/sd@0,15</A>       15. c3t0d22 <HITACHI-OPEN-E-SUN-2114 cyl 19757 alt 2 hd 15 sec 96>           <A>/pci@8,600000/JNI,FCR@1/sd@0,16</A>   이렇게 많이 나오는데요!! 이걸 어떻게 판단하면 좋을까요? 하드디스크가 16개 인가요? 크게 c1t#d#, c2t#d#, c3t#d# 이렇게 3 그룹으로 나눠서 보니까 그룹별로 backup 용량이 모구 같게 나옵니다. 답변 부탁 드립니다.
