Red Hat

Hey everyone. Right now I am working through Red Hat's online storage reconfiguration guide for a project that we're working on. For removing storage paths to a volume using multipaths, it says that the first step is to type:

Code:

echo offline> /sys/block/sda/device/state

Does it actually mean SDA? Or should I modify it to match the device in question?

I ask because further down the same guide it says specifically:

Code:

echo 1 >/sys/block/device-name/device/delete

I can't tell if this is an issue with their documentation, or not. Wouldn't SDA be the first scsi disk, not the particular disk I'm working on? I just want to make sure it doesn't have a special meaning in this case. Thanks!

For your reference, the guide is here:
6. Removing a Path to a Storage Device

Again, thanks for any help. I want to really understand this before I tinker too much.

It is the "general procedure," so I'd say not to write "offline" to sda's device state, if it is not sda you want to bring offline.

Confirmed, I just did it with the sdX device listed by each path in multipath -l. Worked like a bell. Tested both adding and removing devices with no issues.
