This was fixed on the 2.1 release, when most of pt-summary was rewritten, but was never actually tagged. Also, a belated thanks to Devananda for the patch!

Can you attach the output of MegaCli so we can create a test case?

**Comment from Launchpad by: Devananda van der Veen on: 23-11-2011 23:54:44

I just ran into this as well. The problem is the awk script parsing MegaCli output is looking for "Virtual Disk" but some versions of MegaCli print "Virtual Drive" instead, therefore no device is found.

The fix for this is trivial:

$ diff -c pt-summary pt-summary-new
***************

•  

  •  

    • 714,720 ****
      echo " VirtualDev Size RAID Level Disks SpnDpth Stripe Status Cache"
      echo " ========== ========= ========== ===== ======= ====== ======= ========="
      awk '
      ! /^Virtual Disk:/ {
      device = $3;
      devicenames[device] = device;
      }

    • 714,720 ----
      echo " VirtualDev Size RAID Level Disks SpnDpth Stripe Status Cache"
      echo " ========== ========= ========== ===== ======= ====== ======= ========="
      awk '
      ! /^Virtual (Drive|Disk):/ {
      device = $3;
      devicenames[device] = device;
      }

Now, the output I get is not perfect, but it is better than nothing:

VirtualDev Size RAID Level Disks SpnDpth Stripe Status Cache
========== ========= ========== ===== ======= ====== ======= =========
0 0 (:-1-0) 2 Depth-3 WB, RA

With a few more changes, I can get all columns populated

VirtualDev Size RAID Level Disks SpnDpth Stripe Status Cache
========== ========= ========== ===== ======= ====== ======= =========
0 1.633 TB 0 (:-1-0) 2 Depth-3 64 KB Optimal WB, RA

$ diff -c pt-summary pt-summary-new
