18. 3.磁带状态的变化，从拔盘，到插盘的过程中。
19. Device |Normal|Damage|Rebuild|Normal
20. Virtual Drive |Optimal|Degraded|Degraded|Optimal
21. Physical Drive |Online|Failed –> Unconfigured|Rebuild|Online
22. 4.查看磁盘缓存策略
23. #/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -Cache -L0 -a0
24. or
25. #/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -Cache -L1 -a0
26. or
27. #/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -Cache -LALL -a0
28. ro
29. #/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -Cache -LALL -aALL
30. ro
31. #/opt/MegaRAID/MegaCli/MegaCli64 -LDGetProp -DskCache -LALL -aALL
32. 5.设置磁盘缓存策略
33. 缓存策略解释：
34.
35. WT (Write through
36. WB (Write back)
37. NORA (No read ahead)
38. RA (Read ahead)
39. ADRA (Adaptive read ahead)
40. Cached
41. Direct
42. 例子：
43. #/opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp WT|WB|NORA|RA|ADRA -L0 -a0
44. or
45. #/opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp -Cached|-Direct -L0 -a0
46. or
47. enable / disable disk cache
48. #/opt/MegaRAID/MegaCli/MegaCli64 -LDSetProp -EnDskCache|-DisDskCache -L0 -a0
49. 6.创建一个 raid5 阵列，由物理盘 2,3,4 构成，该阵列的热备盘是物理盘 5
50. #/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -Hsp[1:5] -a0
51. 7.创建阵列，不指定热备
52. #/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -a0
53. 8.删除阵列
54. #/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdDel -L1 -a0
55. 9.在线添加磁盘
56. #/opt/MegaRAID/MegaCli/MegaCli64 -LDRecon -Start -r5 -Add -PhysDrv[1:4] -L1 -a0
57. 10.阵列创建完后，会有一个初始化同步块的过程，可以看看其进度。
58. #/opt/MegaRAID/MegaCli/MegaCli64 -LDInit -ShowProg -LALL -aALL
59. 或者以动态可视化文字界面显示
60. #/opt/MegaRAID/MegaCli/MegaCli64 -LDInit -ProgDsply -LALL -aALL
61. 11.查看阵列后台初始化进度
62. #/opt/MegaRAID/MegaCli/MegaCli64 -LDBI -ShowProg -LALL -aALL
63. 或者以动态可视化文字界面显示
64. #/opt/MegaRAID/MegaCli/MegaCli64 -LDBI -ProgDsply -LALL -aALL
65. 12.指定第 5 块盘作为全局热备
66. #/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0
67. 13.指定为某个阵列的专用热备
68. #/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Set [-Dedicated [-Array1]] [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0
69. 14.删除全局热备
70. #/opt/MegaRAID/MegaCli/MegaCli64 -PDHSP -Rmv -PhysDrv[1:5] -a0
71. 15.将某块物理盘下线/上线
72. #/opt/MegaRAID/MegaCli/MegaCli64 -PDOffline -PhysDrv [1:4] -a0
73. #/opt/MegaRAID/MegaCli/MegaCli64 -PDOnline -PhysDrv [1:4] -a0
74. 16.查看物理磁盘重建进度
75. #/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ShowProg -PhysDrv [1:5] -a0
76. 或者以动态可视化文字界面显示
77. #/opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ProgDsply -PhysDrv [1:5] -a0
78.
79. 磁带状态的变化，从拔盘，到插盘的过程中：
80. Device |Normal|Damage|Rebuild|Normal
81. Virtual Drive |Optimal|Degraded|Degraded|Optimal
82. Physical Drive |Online|Failed –> Unconfigured|Rebuild|Online
