The function parsing the RAID logical volumes in the HP module did not
manage the case where disks were set in JBOD mode, thus having no RAID
array set.
This patch fixes this by checking if arrays are defined on pdisks before
parsing the logical disks.
Also added returncode read when executing the RAID related commands to
raise a more precise error.
This patch brings some of the physical and virtual drive attributes as
`custom_fields` to the disks inventory.
The goal is to have this information present to ease disks maintenance
when a drive becomes unavailable and its attributes can't be read anymore
from the RAID controller.
It also helps to standardize the extended disk attributes across the
different manufacturers.
As the disk physical identifers were not available under the correct
format (hexadecimal format using the `xml` output as opposed as `X:Y:Z` format
using the default `list` format), the command line parser has been
refactored to read the `list` format, rather than `xml` one in the
`omreport` raid controller parser.
As the custom fields have to be created prior being able to register
the disks extended attributes, this feature is only activated using the
`--process-virtual-drives` command line parameter, or by setting
`process_virtual_drives` to `true` in the configuration file.
The custom fields to create as `DCIM > inventory item` `Text` are described
below.
NAME LABEL DESCRIPTION
mount_point Mount point Device mount point(s)
pd_identifier Physical disk identifier Physical disk identifier in the RAID controller
vd_array Virtual drive array Virtual drive array the disk is member of
vd_consistency Virtual drive consistency Virtual disk array consistency
vd_device Virtual drive device Virtual drive system device
vd_raid_type Virtual drive RAID Virtual drive array RAID type
vd_size Virtual drive size Virtual drive array size
In the current implementation, the disks attributes ore not updated: if
a disk with the correct serial number is found, it's sufficient to
consider it as up to date.
To force the reprocessing of the disks extended attributes, the
`--force-disk-refresh` command line option can be used: it removes all
existing disks to before populating them with the correct parsing.
Unless this option is specified, the extended attributes won't be
modified unless a disk is replaced.
It is possible to dump the physical/virtual disks map on the filesystem under
the JSON notation to ease or automate disks management. The file path has to
be provided using the `--dump-disks-map` command line parameter.
This patch adds the ability to detect and manage GPU and Disk expansion
bays, and either add their internal components into the device
corresponding to the blade server, or into a dedicated device.
It takes advantage of the work made by @cyrinux on GPU bays management, and
applies the same principle to the external disk bays, but harmonize the
inventory management:
- If no argument is specified on the command line, the GPU cards, RAID
controllers and their attached disks are added in the blade device,
and the device corresponding to an expansion device is deleted.
- If the `--expansion-as-device` option is specified on the command
line, a dedicated device corresponding to the expansion bay is
created, and the GPUs, RAID card and attached disks are removed from
the blade device and added to the expansion device.
* Some messages about the cache for example, with indentation level 0 break the parsing.
I ignore line indentation if indentation level and line dont match REGEXP_CONTROLLER_HP.
