An administrator is adding an NVMe device to an existing storage pool They provide the following details in the Add Storage Device to SDS dialog box…

The provided device path, /dev/disk/by-id'DellExpressFlash..., is syntactically incorrect for a Linux-based operating system on which the Storage Data Server (SDS) runs. A valid path requires a forward slash (/) as a separator between directory components (e.g., /dev/disk/by-id/DellExpress...). The presence of a single quote (') instead of a forward slash after /by-id makes the path invalid. The PowerFlex software will be unable to resolve this path to locate the physical device, causing the add device operation to fail immediately upon path validation.

"Adding a device to an SDS".

The --addsdsdevice command requires the --sdsdevicepath parameter. The document specifies this must be "The path to the device to be added

" which implies a syntactically valid path that the underlying operating system can resolve. The provided path is not valid.

The guide also specifies for the --devicename parameter that "The name can contain alphanumeric characters

underscores ()

and hyphens (-)." This confirms the name provided in the question is also invalid

but the path error is the primary blocker.

Reading 10: The UNIX Time-Sharing System

Section 5.4 "A File System".

This and similar academic materials on operating systems establish that hierarchical file systems like the one used by Linux use the forward slash (/) as a path component separator. A path containing /dev/disk/by-id'...' violates this fundamental syntax.
