Hi
I have the below--
disk 460 0/0/14/1/1.11.183.192.0.0.0 sdisk NO_HW DEVICE HITACHI OPEN-V
disk 461 0/0/14/1/1.11.183.192.0.0.1 sdisk NO_HW DEVICE HITACHI OPEN-V
disk 275 0/0/14/1/1.11.183.192.0.0.6 sdisk NO_HW DEVICE HITACHI OPEN-V-CM
disk 147 0/0/14/1/1.11.183.192.0.8.3 sdisk NO_HW DEVICE HITACHI OPEN-V
disk 148 0/0/14/1/1.11.183.192.0.8.4 sdisk NO_HW DEVICE HITACHI OPEN-V
disk 150 0/0/14/1/1.11.183.192.0.8.5 sdisk NO_HW DEVICE HITACHI OPEN-V
disk 153 0/0/14/1/1.11.183.192.0.8.6 sdisk NO_HW DEVICE HITACHI OPEN-V
disk 154 0/0/14/1/1.11.183.192.0.8.7 sdisk NO_HW DEVICE HITACHI OPEN-V
disk 155 0/0/14/1/1.11.183.192.0.9.0 sdisk NO_HW DEVICE HITACHI OPEN-V
disk 18 0/0/14/1/1.11.183.192.0.14.2 sdisk NO_HW DEVICE HITACHI OPEN-V
disk 20 0/0/14/1/1.11.183.192.1.0.2 sdisk NO_HW DEVICE HITACHI OPEN-V
Now my question is that do I need to cross check before removal or whenever I see this in a system I can directly go for hardware path removal like below
rmsf -H 0/0/14/1/1.11.183.192.0.0.0
Thank you in advance
regards

SolutionThe NO_HW tag means that although the paths existed at sometime in the past, they have been removed from this computer's connections. This would be the case if the disk array was powered down, or the mapping from the Hitachi has been deleted for this system. There is no concern to remove these paths and devices using rmsf. If these paths are restored sometime in the future, just run ioscan, then insf to recreate the device connections.
If you don't know why these NO_HW paths exist, you can run a vgdisplay command and look for error messages about missing devices.

Re: hardware path removal LUN
Hi Mr.Bill
Exactly I want to know this only. As I was asked to cross check before removing these paths as wrong removal may cause issue in the system.Thank you very much.
"Now I can remove these without any fearing"
