[CentOS] Correct way to change I/O scheduler in a iSCSI dev

Hi,

What's the correct way to change configuration parameters for an iSCSI device? For example I/O scheduler, max_sectors_kb, etc...

I could add commands to the S99local script:

echo noop > /sys/block/sdb/queue/scheduler echo 64 > /sys/block/sdb/queue/max_hw_sectors_kb

Unfortunately, iSCSI device names might change from sdb to, say, sdc (server reboot, iSCSI target reconnection). If this happens, customizations would be lost or applied to a different device.

Any workaround for this using centOS? sysctl, udev, anything else? It also may be applied to Fiber Channel devices..

Thanks!
