dear all,

I want to understand how GNR/GSS/ESS stores information about the pdisk location
I looked in the configuration file

/var/mmfs/gen/mmfsNodeData
/var/mmfs/gen/mmsdrfs
/var/mmfs/gen/mmfs.cfg

but no location of pdisk

this is real scenario of unknown location
this is the output from GNR/GSS/ESS
-----------------------------------
[root at ess1 ~]# mmlspdisk BB1RGR --not-ok
pdisk:
replacementPriority = 2.00
name = "e2d3s11"
device = ""
recoveryGroup = "BB1RGR"
declusteredArray = "DA2"
state = "missing/noPath/systemDrain/noRGD/noVCD/noData"
capacity  = 3000034656256
freeSpace = 2997887172608
location = ""
WWN = "naa.5000C50056717727"
server = "ess1-ib0"
reads = 106800946
writes = 10414075
IOErrors = 1216
IOTimeouts = 18
mediaErrors = 0
checksumErrors = 0
pathErrors = 0
relativePerformance = 1.000
userLocation = ""
userCondition = "replaceable"
hardware = "   "
hardwareType = Rotating 7200
nPaths = 0 active 0 total
nsdFormatVersion = Unknown
paxosAreaOffset = Unknown
paxosAreaSize = Unknown
logicalBlockSize = 512
-----------------------------------
I begin change the Hard disk
mmchcarrier BB1RGR --release --pdisk "e2d3s11"
I have this error
Location of pdisk e2d3s11 of recovery group BB1RGR is not known.
i know the location of the Hard disk
i know the location of the Hard disk from old mmlspdisk file
mmchcarrier BB1RGR --release --pdisk "e2d3s11" --location "SV30708502-3-11"

Location of pdisk e2d3s11 of recovery group BB1RGR is not known.
I read in the official documentation
6027-3001 [E] Location of pdisk pdiskName of recovery
group recoveryGroupName is not known.
Explanation: IBM Spectrum Scale is unable to find the
location of the given pdisk.
User response: Check the disk enclosure hardware.
