DEVICE_NAMING is a bit mask system parameter indicating whether port allocation classes are used in forming SCSI device names on Alpha and Integrity servers.
Definition
| Bit | Definition |
|---|---|
| 0 | If 1, enable new naming. |
| 1 | Must be 0. This bit is Reserved for use by VSI. |
| 2 | If 1, cloned device unit numbers wrap after 9999(not 65472). |
| 3 | If 1, cloned device unit numbers wrap after 32767(not 65472). |
Even if both bits are zero, device unit numbers will wrap after 9999 if "nodename$" is prefixed to the name of the device in question (e.g. VMS123$DKA100:); devices whose drivers support larger device numbers will wrap after 65472 (or 32767 if bit 3 is set) only if the nodename is not built into the device name.
