Hi Ramanujam1 ;

I'm facing the same problem with HDLM 5.8 for OCR/Voting devices. How did you solve the problem. Please let me know.
Regards..

I'm not familiar with the HDLM software, but you can list the valid attributes for an ODM object via:

1. lsattr -Rl dlmfdrv300 -a dlmrsvlevel

Good luck.

Not sure if this is what you really need...

1. chdev -l /dev/hdisk# -a reserve_policy=no_reserve -P <-- for all hdisks under dlmfdrvN
2. chdev -l /dev/dlmfdrvN -a reserve_lock=no_reserve -P

NOTE: Changes will only go into effect upon reboot.

Above is true for MPIO but it looks like the reserve_lock setting
on the HDLM devices, by default, is not user-modifiable....
