使用 nbperfchk 验证 NetBackup Appliance 上的磁盘性能
Nbperfchk 命令还可用于测试存储写入速度。如果磁盘写入速度下降至 130 MB/s 以下，则设备的基础存储配置可能存在潜在问题，应联系 技术支持以进行调查。要使用 nbperfchk 测试磁盘写入速度，请将要测试的设备存储路径指定为 nbperfchk 的输出路径（-o 参数值）：
表：设备存储路径
|
设备存储 |
存储路径 |
示例 |
|---|---|---|
|
52xx MSDP |
|
nbperfchk -I zero: -o /disk/nbperfchk.tst -s 64g -syncend |
|
52xx AdvancedDisk |
|
nbperfchk -I zero: -o /advanceddisk/advol/nbperfchk.tst -s 64g -syncend |
以下是 nbperfchk 到 MSDP 和 AdvancedDisk 存储的写入测试运行示例：1) Nbperfchk 到 MSDP 的写入测试：
symprimary-a.Support> Nbperfchk run
Please enter options:
nbperfchk -I zero: -o /disk/nbperfchk.tst -s 64g
-syncend
