#LOCAL DISK MANAGER INSTALL#

So what does the error “you must initialize a disk before logical MBR or GPT” mean? So, in the case of a new disk, it's okay, as initialization is required for your convenience (using it, you can install the file system you prefer). We have hundreds of VM's running and this is the first issue like this we have encountered.About the issue: “You must initialize a disk before the logical disk manager can access it”īasically, this problem occurs with a completely new disk, but sometimes it happens with an old disk when you connect to it. Ping times between campuses is roughly 2ms, and firewalls are not an issue.

Yes, both servers are virtual, connected via fiber channel, to their own VNX storage groups.

The replicated storage cannot be located on the drive containing the Windows operating system folder.

Asynchronous replication does not have a latency recommendation.

A network between servers with enough bandwidth to contain your IO write workload and an average of =5ms round trip latency, for synchronous replication.

#LOCAL DISK MANAGER PLUS#

Appropriate firewall and router rules to allow ICMP, SMB (port 445, plus 5445 for SMB Direct) and WS-MAN (port 5985) bi-directional traffic between all nodes.

At least one ethernet/TCP connection on each server for synchronous replication, but preferably RDMA.

The physical storage must have the same sector sizes on all the The physical storage must have the same sector sizes on all the data disks.

Each set of storage must allow creation of at least two virtual disks, one for replicated data and one for logs.

You will make each storage set available only to each of the servers, with no shared access. The storage should contain a mix of HDD and SSD media.

Two sets of storage, using SAS JBODs, fibre channel SAN, iSCSI target, or local SCSI/SATA storage.

Please try to run PowerShell “get-physicaldisk” to check if you can see all the logical drives.Īnd do you meet all the Prerequisites mentioned in the article you offered.

May I ask what exactly error message do you get? Please also check the event viewer. I'm stuck and cannot find any applicable support on TechNet or google There is nothing in Application or System logs to indicate a problem.įor grins, I deleted the 3.1 TB drive and started over without success. I can create, edit, and delete a text file on drive E and F. but in Server Manager,įile and Storage Services the only thing that shows is the original 60GB C 'OS' drive. I can see the drives in Disk Management, I can see the drives in 'This PC'. When I ran the SRTopology test, it told me that it could not find drive E or F. 3TB going to 'data' and 100GBĭedicated to 'logs' ( drive E and F, respectively) According to the directions, applicable roles were installed, updates run, and a secondary 3.1 TB drive was created with the GPT format. I have built a virtual - Server 2016 DataCenter - server at each campus. I am beginning the process of setting up a Storage Replica environment between two campuses, using
