Storage capacity reporting has become a tedious task these days unless we don’t have tools in place. These tools are not as cheap we can think of. There are additional layers added to it to hype and increase its value in market. But if customer ask a storage admin to run the report manually then its a nightmare for the admins.
We always want to go by the easy way which means GUI / EMC Unisphere but for reporting this doesn’t helps to customize and fulfill the customer requirements . EMC SYMCLI / Solutions Enabler can be used effectively here to address this issue. We can use SYMCLI to automate these manual reports. By means of automation, we can ensure quality, timely and error-free reports are generated which can be scheduled via CRON or Tasks Scheduler to send it directly to the stakeholders. SYMCLI built-in supports XML formatted output of the commands which would become easier to parse the information using XML supported programming language.
I’ve developed PERL scripts to generate Storage Pool capacity and Disk capacity report for multiple VMAX storage arrays which are managed from the SYMCLI / Solutions Enabler server. Following are the benefits of using this script.
1. Generates Pool capacity report for all storage arrays which has columns – SYM ID,MODEL,TOTAL USABLE POOL CAPACITY TB,TOTAL USED POOL CAPACITY TB,TOTAL FREE POOL CAPACITY TB, TOTAL POOL UTILIZATION %, TOTAL POOL SUBSCRIBED %
2. Generates Disk capacity report for all storage arrays which has columns – SYM ID,MODEL,TOTAL EFD,TOTAL FC_SAS,TOTAL SATA_NLSAS,FORMATTED EFD CAPACITY GB,FORMATTED FC_SAS CAPACITY GB,FORMATTED SATA_NLSAS CAPACITY GB, TOTAL FORMATTED CAPACITY GB, UNFORMATTED EFD CAPACITY GB,UNFORMATTED FC_SAS CAPACITY GB,UNFORMATTED SATA_NLSAS CAPACITY GB,TOTAL UNCONFIGURED CAPACITY GB,TOTAL UNFORMATTED CAPACITY GB
Output generated from the scripts will be in the form of CSV format. This is information can be plugged into desired format and generate reports with Pivots, charts etc…
Please find below sample output for reference.

Disk Capacity Report:
P.S: I’ve removed VMAX serial number for various factors 🙂
If interested, please reach out to me to get these PERL scripts.
