Dell Unity：通过 Unisphere CLI 管理 FAST VP 自动分层位置调整

• 提供有关通过 Unisphere CLI （UEMCLI） 管理 Unity 混合存储池中的自动分层的信息
• 简要说明 FAST VP

• Fast VP 监视分层池中数据的使用情况。分层池是配置了多个驱动器类别（SAS Flash 2 或 SAS Flash 3 以及 SAS 或 NL-SAS）的异构池。
• 根据分层策略，使用监视统计信息以 256 MB 粒度自动将数据区块重新定位到池中的其他层。 
• 跨分层和非分层池中的驱动器执行负载平衡

• 查看系统 FAST VP 信息：

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/fastvp show -detail

1: Paused = no
Schedule enabled = yes
Frequency = Every Mon, Fri at 22:30 until 8:00
Rate = high
Data to move up = 4947802324992 (1.5T)
Data to move down = 4947802324992 (1.5T)
Data to move within = 4947802324992 (1.5T)
Estimated scheduled relocation time = 7h 30m

• 编辑系统 FAST VP 信息：

Format :
uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/fastvp set [-schedEnabled {yes | no}] [- days ] [-at ] [-until ] [-rate {low | medium | high}] [-paused {yes | no}]

For example, the following command changes the data relocation schedule to run on Mondays and Fridays from 23:00 to 07:00:
uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/fastvp set -schedEnabled yes -days "Mon,Fri" -at 23:00 -until 07:00

• 编辑池 FAST VP 设置，使其遵循系统级计划或不遵循（使其处于手动位置调整状态）：

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/pool/fastvp {-pool | -poolName } set -schedEnabled {yes | no}

• 在池上启动数据位置调整：

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/pool/fastvp {-pool | -poolName } start [-rate {low | medium | high}] [-endTime ]

Default rate is medium
Default end time is 8 hours after start
If you want to edit the end time, add the time in HH:MM format

• 停止池上的数据位置调整：

uemcli -d 10.0.0.1 -u Local/joe -p MyPassword456! /stor/config/pool/fastvp {-pool | -poolName } stop
