    Hi,

    using sddpcm in vio client lpar with 4 vfc adapters

    3 disks, 4 pathes each

    following problem:
    
# lspath Missing hdisk0 fscsi0 Missing hdisk2 fscsi0 Enabled hdisk1 fscsi0 Enabled hdisk0 fscsi1 Enabled hdisk0 fscsi2 Enabled hdisk2 fscsi2 Enabled hdisk2 fscsi1 Enabled hdisk1 fscsi1 Enabled hdisk1 fscsi2 Enabled hdisk0 fscsi3 Enabled hdisk2 fscsi3 Enabled hdisk1 fscsi3   # pcmpath query adapter   Total Dual Active and Active/Asymmetric Adapters : 4   Adpt#    Name    State     Mode             Select     Errors  Paths  Active 0  fscsi2   NORMAL   ACTIVE              78661          7      3       3 1  fscsi1   NORMAL   ACTIVE              90112          6      3       3 2  fscsi0   NORMAL   ACTIVE              38079          3      1       1 <<--- 3  fscsi3   NORMAL   ACTIVE              77664          5      3       3


    from lspath manual:
    missing Indicates that the path was defined in a previous boot, but it was not detected in the most recent boot of the system.

    how can the missing pathes of hdisk0 and hdisk2 through fscsi0 be restored?

    not successful with this one
    
# lspath -l hdisk0   -F
"connection:parent:path_status:status" 50050763091809bb,40c040b000000000:fscsi0:Missing:N/A 50050763091089bb,40c040b000000000:fscsi1:Available:Enabled 50050763093809bb,40c040b000000000:fscsi2:Available:Enabled 50050763093089bb,40c040b000000000:fscsi3:Available:Enabled   # mkpath -l hdisk0 -p fscsi0 -w 50050763091809bb,40c040b000000000 Method error (/etc/methods/cfgscsidisk): 0514-077 Cannot perform the requested function because none of the specified paths match those 

for the specified device.


    any ideas? thanks

    what if you would run cfgmgr?

    or disable+remove (rmpath) the not working paths and after that run cfgmgr?

    if they are still missing then I think you should check your affected storage ports
