Over the years I collected a number of useful CLI commands to control the DMX / VMAX machines I worked with. Even though nowadays Unisphere for VMAX is a useful tool, nothing really beats the command line!
CLI forever!
Why? It provides the output you need when running the commands you type. There’s no need to search for the right pull down menu, since you directly type whatever you need.
Create devices
| Size | Number | Script (type this in a txt file and run a symconfigure command with -f file.txt) |
| 22GB | 6 | create dev count=6, size=24000 CYL, emulation=FBA, config=TDEV, binding to pool=FC, preallocate size=24000 CYL; |
| 44GB | 12 | create dev count=12, size=48000 CYL, emulation=FBA, config=TDEV, binding to pool=FC, preallocate size=48000 CYL; |
| 55GB | 200 | create dev count=200, size=60000 CYL, emulation=FBA, config=TDEV; binding to pool=FC, preallocate size=600000 CYL; |
| 77GB | 6 | create dev count=6, size=84000 CYL, emulation=FBA, config=TDEV, binding to pool=FC, preallocate size=84000 CYL; |
If you don’t want to preallocate the space, simply leave that part out.
Symdev show
Every little detail on symdevs can be viewed using the infamous “symdev show” command. Suppose you want to see the naa-number which you can also see in VMware VCenter, run the following command (mind the number of spaces before the colon):
| symdev -sid 1234 show 567 | find “Device WWN :” | Device WWN : 60000960000305701165533144353499 |
Symdev change
If you need to enlarge a tdev you don’t need to add meta members anymore on VMAX3 or VMAX All Flash. Simply change its size and you’re done!
| symdev -sid 123 modify AA -tdev -cap 3072 -captype gb |
This will change TDEV AA size to 3072 GB
Naming symdevs
