3PAR File Persona无法配置或提示 block-only 解决方法

HPE 3PAR一些中高端型号最新固件中已经集成了 File persona 功能，也就是以后我们不需要再额外购买单独的NAS机头。
但是在配置的过程中发现居然找不到File persona这个功能。
新购设备为3Par 8400 包含所有license的机型。
初始化完存储后，登陆SMCC管理台根本找不到File persona 选项。
通过SSH工具连接，使用命令startfs 出现以下提示：
File Persona cannot be configured while the system is set to block-only mode. Please contact HPE Support for assistance."
These error messages occur because the 3PAR system Persona Profile setting is set to "block-only."
通过查询KB，发现存储如果没有单独配置PCI槽位的网卡，系统默认把File persona禁用，也就是为什么我们无法配置File persona的原因。
而由于一些成本的考虑，往往我们会把3PAR上自带的remote copy口用于NAS的数据口（虽然官方是不推荐的）。
如果要强制开启File persona 可才考以下命令：

  1. 使用命令 "showsys" 查看配置，如下：
    cli% showsys -param
    PersonaProfile : block-only
  2. 使用 "shownode" 查看控制器的配置，如下：
    cli% shownode –PersonaProfile
    Node, Config, Current
    0, block-only, block-only
    1, block-only, block-only
  3. 使用 "setsys" 更改配置为block-preferred，如下：
    cli% setsys PersonaProfile block-preferred

另外附上KB内容供大家参考：

RESOLUTION
Support response instructions for specific 3.2.2 MU3 and 3.2.2 MU4 error messages:

  1. Check if the array has one of the supported add-on NICs installed.

  2. • HPE 3PAR StoreServ 7000c 2-port 10Gbps Ethernet Adapter E7X96A
    • HPE 3PAR StoreServ 7000c 4-port 1Gbps Ethernet Adapter E7X97A
    • HPE 3PAR StoreServ 8000 4-port 1Gbps Ethernet Adapter - H6Z05A
    • HPE 3PAR StoreServ 8000 2-port 10Gbps Ethernet Adapter - E7Y70A
    • HPE 3PAR StoreServ 20000 2-port 10Gbps Ethernet Adapter for File Persona - C8S95A
    • HPE 3PAR StoreServ 20000 2-port 10Gbps Upgrade Ethernet Adapter for File Persona - C8S99A

  3. If supported NICs are installed, change the PersonaProfile setting to "block-preferred" per the PersonaProfile setting change procedure below and refer the customer to the File Persona Best Practices Guide and File Persona Support Matrix for deployment best practices and supported limits.
  4. If NO supported NICs are installed, then check if the array has empty PCI slots available.
  5. If available PCI slots exist, recommend the customer contact an HPE Sales Representative to discuss their file requirements and purchase a File Persona license and appropriate NICs. Communicate to the customer that the NIC installer would change the PersonaProfile to "block-preferred" as part of the NIC service delivery.
  6. If available PCI slots DO NOT exist, File Persona is licensed, and the customer wants to use an on-board RCIP port for File Persona instead of add-on NICs, then caution the customer about the performance and availability constraints of the RCIP port. Encourage them to discuss their use case with their HPE Sales Representative, if they have not done this already, and ask them if they still want to proceed.
    • If yes, then change the PersonaProfile setting to "block-preferred" per the procedure below, and point the customer to follow the File Persona Best Practices Guide and File Persona Support Matrix for deployment best practices and supported limits.
    • If no, then inform the customer that File Persona cannot be enabled and to contact their HPE Sales Representative to discuss alternative file serving solutions from HPE.

PersonaProfile setting change procedure:
To change the PersonaProfile setting from block-only to block-preferred, use the "setsys PersonaProfile block-preferred" CLI command. The CLI options for setting and viewing the profile values are hidden.

  1. View the configured profile using "showsys"
    a. cli% showsys -param

  2. • PersonaProfile : block-only

  3. View the Configured and Current setting using "shownode"
    a. cli% shownode –PersonaProfile

  4. • Node, Config, Current
    • 0, block-only, block-only
    • 1, block-only, block-only

  5. Set the "sysparm" profile value using "setsys" 1.cli% setsys
    a. PersonaProfile block-preferred
    NOTE:
    • Setting or changing the profile across the cluster requires rebooting each node one at a time.
    • If File Persona is enabled, then the profile cannot be set to "block-only."
    • If the profile is set to "block-only," then "startfs" is not allowed until the profile is changed to "block-preferred," and all nodes are rebooted.
    • Arrays that do not support File Persona always show up in the "block-only" profile, and the profile cannot be changed.
