23.8.1 Prior confirmation

First, confirm the states of the current primary MDS and the secondary MDS by using the sfcrsinfo(1M) command.

# sfcrscinfo -m /dev/sfdsk/gfs/rdsk/volume1
/dev/sfdsk/gfs/dsk/volume1:
FSID  MDS/AC  STATE  S-STATE  RID-1  RID-2  RID-N  hostname
  1   MDS(P)   wait     -       0      0      0     host1
  1   AC        run      -       0      0      0     host1
  1   MDS(S)   run      -       0      0      0     host2
  1   AC        run      -       0      0      0     host2
  1   MDS(I)   imag     -       0      0      0     host3
  1   AC        run      -       0      0      0     host3
  1   MDS(I)   imag     -       0      0      0     host4
  1   AC        run      -       0      0      0     host4

First, confirm the following:

• The file system must be mounted on the node of the primary server.

  You can confirm this by checking that STATE and S-STATE of the Access Client (AC) on host1, that is a hostname of MDS(P), are "run" and "-", respectively.

• The file system must be mounted on the node on the secondary server.

  You can confirm this by checking that STATE and S-STATE of the Access Client (AC) on host2, that is a hostname of MDS(S), are "run" and "-", respectively.

• The node of the primary MDS and its state is "run" and "-".

  The primary MDS is running normally on host2 for which STATE and S-STATE are "run" and "-" in the above example.
  Note that, since the primary server is equivalent to host1 that is displayed as MDS(P), the primary MDS is running on a node other than the defined host.

• The node of the secondary MDS and its state is "wait" and "-".

  The secondary MDS is running normally on host1 for which STATE and S-STATE are "wait" and "-" in the above example.
  Note that, since the secondary server is equivalent to host2 that is displayed as MDS(S), the secondary MDS is running on a node other than the defined host.
