Hi,
Does anybody of you have a list of the status codes ? I wasn't
able to find anything on the internet, and IBM tech
support was unable to hand out anything. They said that those
informations are protected and they can't out anything without
a NDA. Bullshit !
Currently we only see 'int' values in ipsstat, which is not
really helpful if you have IBM on the phone and they ask
what status your drive has. The speak about 3-letter codes,
and you tell them: It has state 8 ...
I was able to get some of them myself, but it would be
cool if you can fill in the rest of the missing values.
Any ideas ? I'd like to commit this to ips.h
to have more useful information available.

------------------------------------------------------------------
Abr: State: Number:
------------------------------------------------------------------
RDY Ready ... ?
RDY appears as the status of a drive that the RAID adapter detects as installed,
spun up, but not configured in an array.
------------------------------------------------------------------
ONL Online 137 ?
Online, a drive that RAID adapter detects as installed, operational, and
configured into an array appear as this state.
------------------------------------------------------------------
RBL Rebuilding ...
A drive in this state is being rebuilt. Only the IBM ServeRAID Adapter has this
state. A physical hard drive can enter the RBL state if one of the following
conditions occurs: A good working drive replaces a DDD drive that is part of the
critical logical drive. At the end of a successful rebuild, the state of the
physical drive changes to ONL, and the state of the corresponding logical drives
changes to OKY.
The HSP or standby hot-spare (SHS) drive is added to the array and the state
changes from HSP or SHS to RBL. At the same time, the DDD drive is removed from
the array and its state changes to DHS from DDD. The adapter then automatically
reconstructs data in the RBL drive. The state of the corresponding logical drive
remains CRT (if the RAID level is 1 or 5) or OFL during the rebuild process.
When the rebuild completes successfully, the device state changes from RBL to
ONL and the logical drive state changes from CRT to OKY.
A ready (RDY) or standby (SBY) drive replaces a DDD drive that is part of the
critical logical drive. The state of the RDY or SBY drive becomes RBL. When the
rebuild completes successfully, the state changes to ONL. The DDD drive is
removed from the logical drive and becomes DHS
------------------------------------------------------------------
HSP Hot Spare 133
(IBM ServeRAID & ServeRAID II)
A hot-spare (HSP) drive is a drive designated to be a replacement for the first
DDD drive that occurs. The state of the drive appears as HSP. When a DDD drive
occurs and a HSP is defined, the hot-spare drive takes over for the drive that
appears as DDD. The HSP drive is rebuilt to be identical to the DDD drive.
During the rebuilding of the HSP drive, this drive changes to the RBL state. The
RBL state will turn to ONL once the drive is completely rebuilt and fully
operating for the DDD drive.
------------------------------------------------------------------
DHS Spare Defunct 8 or 4 ?
A hot-spare or standby hot-spare drive (see below) enters the defunct hot-spare
(DLIS) state if it fails to respond to the adapter commands. Once a DHS drive is
replaced, its state changes from DHS to HSP. Only the IBM ServeRAID Adapter has
the DHS state.
------------------------------------------------------------------
DDD HW Defunct 8 or 4 ?
The RAID adapter marks an ONL or OFL (RBL if ServeRAID) drive defunct, changing
its status to DDD and removing power from the drive, when one of the following
conditions occur:
* The drive does not respond to commands by a certain timeout value.
* The drive exceeds the number of allowed busy status responses as
specified by the RAID adapter firmware.
* A reassign failure or two successive failures in verification occur when
the RAID adapter tries to recover from a media error reported from the drive.
------------------------------------------------------------------
SBY Standby ... ?
A standby drive is a hard disk drive that the RAID adapter has spun down.
Devices such as tape drives and CD-ROM drives are also considered to be in a
standby state. Only the IBM ServeRAID Adapter has the state.
------------------------------------------------------------------
SHS Standby Hot Spare ... ?
A standby hot-spare is a hot-spare drive that the adapter has spun down. If a
drive becomes defrinet and no suitable hot-spare drive is available, a standby
hot-spare of the appropriate size spins up and enters the RBL state. You must
have at least four hard disk drives if you want a standby hot-spare with RAID-5.
Only the IBM ServeRAID Adapter has the state.
------------------------------------------------------------------
EMP Empty ... ?
No device is present in the bay or the adapter cannot communicate with the
drive. This state is represented with dashes (- - -) on the IBM ServeRAID
configuration screen, or a blank space on the Administration and Monitor screen.
Only the JBM ServeRAID Adapter has this state.
------------------------------------------------------------------
OFL Offline ... ?
Offline, a good drive that replaces a defunct drive in a RAID level I or level 5
array. This drive is associated with the array, but does not contain any data.
Drive status remains OFL during the rebuild phase.
------------------------------------------------------------------
PFA Checksum errors ...
The firmware of a hard drive uses algorithms to track the error rates on the
drive. The drive alerts the user with a Predictive Failure Analysis (PFA) alert
via the RAID administration utility and NetFinity when degradation of drive
performance (read/write errors) is detected. When a PFA alert occurs, physical
replacement of the drive is recommended.
------------------------------------------------------------------
UFM Unformatted ... ?
Unformatted, a drive that requires a low-level formatting before it can be used
in an array. You can start the low-level format by selecting Format Drive from
the RAID Configuration Main Menu.
------------------------------------------------------------------
FMT Reformat in progress ... ?
Format: the drive is being reformatted.
