CICS HPC Rain Cluster - Accessing Data Cluster Wide
When you are accessing data cluster wide you will need to specify the /data name for it. For example; to access the data in /san/cics_sfr you would use: /data/sfr - this path is accessible by all nodes in the cluster.
Another example; when you login to rain and issue df -hT you will get something like the following results:
/dev/mapper/water_vg-water_lv
xfs 3.0T 40G 3.0T 2% /san/cics_water
/dev/mapper/sfr_vg-sfr_lv
xfs 1.5T 1.1T 498G 68% /san/cics_sfr
/dev/mapper/rferraro_vg-rferraro_lv
xfs 1.5T 492G 1.1T 33% /san/cics_rferraro
/dev/mapper/meyers_vg-meyers_lv
xfs 4.0T 33M 4.0T 1% /san/cics_meyers
/dev/mapper/color_vg-color_lv
xfs 492M 25M 467M 6% /san/cics_color
/dev/mapper/yyou_vg-yyou_lv
xfs 4.0T 2.4T 1.7T 58% /san/cics_yyou
/dev/mapper/data1_vg-data1_lv
xfs 9.0T 34M 9.0T 1% /san/cics_data1
/dev/mapper/data2_vg-data2_lv
xfs 80T 6.0T 75T 8% /san/cics_data2
If we wanted to access /san/cics_sfr you can use this path only on the head node. You should, however use the cluster wide path which is /data/sfr. Or, if you are accessing /san/cics_data2 you should use /data/data2.
If you access a compute node and try to access the path /san/cics_sfr you will not be able to access the data. Instead you should use /data/sfr.
/san/cics_water -> /data/water
/san/cics_meyers -> /data/meyers
/san/cics_data1 -> /data/data1
.. etc
