Solution

  • You have to create disk below the steps:

    1) sdb : dd if=/dev/zero of=/sdb count=10240 bs=64k

    sdc : dd if=/dev/zero of=/sdc count=10240 bs=64k

    2) need to create vim stanza.nsds file

    %nsd: device=/sdb

    nsd=nsd3

    servers=gpfs2

    usage=dataOnly

    failureGroup=100

    pool=data

    %nsd: device=/sdc

    nsd=nsd4

    servers=gpfs2

    usage=dataOnly

    failureGroup=100

    pool=data

    3) after that create disk :

    mmcrnsd -F stanza.nsds -v no

    3) mmlsnsd

    File system Disk name NSD servers

    (free disk) nsd3 gpfs2 (free disk) nsd4 gpfs2

    4) create file system and mount point.
