tools like save_config will not supply it. Use of this attribute is therefore discour-

aged.

Device Specifier (dev_spec):

A method that combines the above four types into a single prioritized list of attributes that

refer to a disk. The format is a String, which means the entire method is surrounded by

double quotes. Tools that create this method determine the order of attributes, based upon

which I/O Protocol applies and what release is involved. Attributes are separated by

white space and the value part is surrounded by single quotes. Any embedded single or

double quote characters must be escaped. The following attributes are supported:

WWID=’wwid’

A disk with the speciﬁed World-Wide Identiﬁer wwid is searched for.

PHYS_LOC=’phys_loc’

A disk at the speciﬁed physical location phys_loc is searched for.

HW_PATH=’hw_path’

A disk at the speciﬁed hardware path hw_path is searched for. Pattern matching

expressions are supported as the hw_path.

DEVICE_ID=’device_id’

A disk with the device ID device_id is searched for.

These attributes can then be listed in a prioritized list, as in:

disk["WWID=’wwid’ PHYS_LOC=’phys_loc’ HW_PATH=’hw_path’"]

In this example, Ignite-UX would ﬁrst look for a disk with a WWID of wwid, and if it

could not be found, then it would look for a disk with a PHYS_LOC of phys_loc, and if

that could not be found, then it would look for a disk with a HW_PATH of hw_path and

return that if found. If all attributes are exhausted, then Ignite-UX will ﬁnd a replacement

disk if allow_disk_remap is set to true.

I/O Protocol (protocol):

An I/O protocol type. Not all HP-UX releases support all protocol types listed here.

Some protocol types listed here may not be supported by any HP-UX release and are

included to indicate what the protocol value would be if the protocol is ever supported in

the future. Protocols not supported by an HP-UX release will be ignored. These protocol

type values may be used to construct a protocol list. That list order may be used by some

parameters to indicate a speciﬁc prioritization of I/O adapters and devices for install or

recovery processing. The valid protocol values are:

fibre_channel

I/O protocol type Fibre Channel (FC). The priority order of FC devices con-

nected via the same I/O adapter is based on hardware path (lunpath hardware

path for HP-UX 11.31 and later).

parallel_scsi

I/O protocol type Parallel Small Computer System Interface (SCSI). The prior-

ity order of Parallel SCSI devices connected via the same I/O adapter is based on

SCSI bus priority order (e.g. SCSI address 7 to 0 followed by 15 to 8).

sas I/O protocol type Serial Attached SCSI (SAS). The order of SAS devices con-

nected via the same I/O adapter is based on physical location. Note that hard-

ware path values should not be used for device selection or recovery device

matching since these values are not consistent for the same device from install to

install.

usb I/O protocol type Universal Serial Bus (USB). The order of USB devices is not

yet deﬁned. There is currently no support for USB devices as a target for install

or recovery.
