Need to deleta a path from Securepath.

[Amruth]

Gurus,

We have secure path installed on one of our rp4440 and have a 2 port fiber channel HBA. The HBAs have connection to the EVA5000. We have LUNs assigned and everything is working properly.

Now for high availblity we have another single port Card and wants to remove the one cable from the 2 Port HBA to the new single port HBA.

We are waiting for the SAN team to configure the EVA so that the LUNs presented to the new WWN.

Need to know how can i delete the devices from Secure path so that i can delete the old ones and add the new devices.

I never done this ...if anybody has idea.

Here is the spmgr -display output.

Hi Amruth,

Attached the secure path guide.You can do anything using this ..includes all commandline operations.

regards,

Hi,

you can connect the single port HBA to SAN and present luns from EVA to the new HBA.

you should see 6 paths to each LUN on EVA. (ioscan and insf -e may be required) .

you can then remove cable from one of the dual port HBA. spmgr display will show the path as failed. but for next boot onwards, you'll see 4 working paths to each LUN.

hope this helps

Eventhough i have seen your reply now but your answer is right.

Just reboot the server, it solved the problem. Secure path takes by itsown the paths.
