Learn this information to learn to set up and configure Multipath Input/Out (MPIO) to assert Fiber Channel (FC) LUMs on a Home windows Server 2022.
Overview
To offer redundancy, LUMs are often assigned to the Main and Secondary WWPN of an FC HBA adapter port. Primarily, the FC LUM is assigned to 2 “paths.”
The good thing about multipath LUM task is that if one of many FC HBA ports breaks, the host server can nonetheless entry the disk – resulting in excessive availability.
Nonetheless, with this multipath configuration, the assigned LUM seems as a number of disks in Home windows Disk Administration. Within the screenshot under, the 1024 GB (1 TB) disk is a single Fiber Channel LUM.
Nonetheless, the disk seems to Home windows as two disks. The way in which to make this a single disk is to put in and configure MPIO on the Home windows Server.
The steps under define the small print.
Step 1: Set up the MPIO Home windows Server Function
To put in MPIO utilizing Server Supervisor, observe these steps.
You can too full this activity with PowerShell (run PowerShell as administrator) by working the command under:
Set up-WindowsFeature -Title multipath-io
Putting in with PowerShell is quicker. Nonetheless, should you favor GUI, listed below are the steps:
- From Server Supervisor, click on Handle > Add Roles and Options.
- Proceed clicking Subsequent till you get to the “Choose options” node. Test the “Multipath I/O” checkbox and click on subsequent.
- Lastly, proceed clicking Subsequent, then, on the ultimate web page, click on Set up.
Look ahead to the set up to finish, then, proceed to Step 2 under.
Step 2: Configure MPIO to Declare the FC Disks
1. From Server Supervisor, click on Instruments and choose MPIO.
- Then, click on the “Uncover Multi-Paths” tab, choose the Gadget Id below SPC-3 grievance, and click on Add. Wait till the “MPIO operation accomplished efficiently” message and restart the server.
Step 3: Configure the Claimed Disk in Disk Administration
When the server restarts, open Disk Administration (right-click Begin Menu > Laptop Administration > Disk Administration).
Disk Administration reveals the FC LUM as a single disk.
Convey the disk on-line, Initialize it, and create a quantity as regular,
Lastly, create a quantity (or a number of volumes as you want) and format the disk.
Conclusion
Should you use Fiber Channel HBA, LUMs could seem as a number of disks in Disk Administration. Earlier than you should utilize the disk, you need to first use MPIO to “declare” the disks so they seem as a single disk.
That is achieved by putting in the Home windows Server Multipath I/O characteristic and configuring MPIO. After that, you should utilize the disk nevertheless you want.
I hope that this straightforward information has saved your day. If I saved you tons of time, I’d like to listen to about it. Let me know by responding to the “What this web page useful” under.
