ioscan -m dsf can't display correct mapping information

[Steven Deng]

Hi,

We add several EMC san disks into the server(rx6600, hpux 11.31), and can scan out the new disks through ioscan, but when executing "ioscan -m dsf", it can't display the new mapping information, only few disks mapping are displayed in ioscan -m dsf command. Detailed information is as below:

ioscan, insf are done, and can also use diskinfo to display new disk information, but ioscan -m dsf is not working properly. How to solve this problem?

Thanks in advance!

[Matti_Kurkela]

What's the output of "insf -L -v" on your system?

Perhaps legacy DSFs have been disabled, and the few legacy DSFs are left over from the time before the disabling.

[Steven Deng]

# insf -L -v

insf: Legacy mode is enabled

This indicates the Legacy mode was not disabled before.

The problem still remains.
