Scenario
I have a Fibre Channel card installed on my NAS and iSCSI & Fibre Channel service is disabled. I tried but failed to enable the service remotely using one of these QNAP utilities on another device:
- QNAP vSphere Web Client Plug-in
For example, when using my NAS to create a datastore for the first time in VMware vSphere Web Client. - QNAP Snapshot Agent
For example, when trying to add my NAS on a VMware or Windows server.
Cause
If you have a Fibre Channel (FC) card installed on your NAS, the kernel driver must wait for a response on the FC connection status before iSCSI & Fibre Channel service can be initialized.
The FC connection response may take some time, which can lead to a timeout error resulting in failure to enable the iSCSI & Fibre Channel service.
The long response time could be due to one of these factors:
- You do not have FC cables connected to your NAS.
- The FC cables are not connected to the FC ports on your NAS.
Recommendation
To optimize the speed and efficiency of your FC connection, make sure to connect your FC cables directly to the FC ports on your NAS.
This will reduce the time it takes for the kernel driver to verify the FC connection so that iSCSI & Fibre Channel service can be initialized before timeout.
Tip
- To manually enable iSCSI & Fibre Channel service on your QTS or QuTS hero NAS, log in to your NAS as an administrator, open iSCSI & Fibre Channel, and click the Service toggle switch in the upper-left corner.
- To manually enable iSCSI & Fibre Channel service on your QES NAS, log in to your NAS as an administrator, open Storage Manager, and go to Global Settings > Enable iSCSI and Fibre Channel services.

场景
我在NAS上安装了一张光纤通道卡,并且iSCSI和光纤通道服务被禁用。我尝试使用以下QNAP工具之一在另一台设备上远程启用该服务,但失败了:
- QNAP vSphere Web Client插件
例如,使用我的NAS在VMware vSphere Web Client中首次创建数据存储时。 - QNAP快照代理
例如,尝试在VMware或Windows服务器上添加我的NAS时。
原因
如果在您的NAS上安装了光纤通道(FC)卡,内核驱动程序必须等待FC连接状态的响应,然后才能初始化iSCSI和光纤通道服务。
FC连接响应可能需要一些时间,这可能导致超时错误,从而无法启用iSCSI和光纤通道服务。
响应时间长可能是由于以下因素之一:
- 您的NAS没有连接FC电缆。
- FC电缆没有连接到NAS上的FC端口。
建议
为了优化FC连接的速度和效率,请确保将FC电缆直接连接到NAS上的FC端口。
这将减少内核驱动程序验证FC连接所需的时间,以便在超时之前初始化iSCSI和光纤通道服务。
提示
- 要在QTS或 QuTS hero NAS上手动启用iSCSI和光纤通道服务,请以管理员身份登录到您的NAS,打开iSCSI和光纤通道,然后点击左上角的服务切换开关。
- 要在QES NAS上手动启用iSCSI和光纤通道服务,请以管理员身份登录到您的NAS,打开存储管理器,然后转到全局设置> 启用iSCSI和光纤通道服务。
