Hello all

Although in vSphere Client a capacity of 5.46 TB is visible, I can only use 3.64 TB for a datastore.

Configuration:

- HP Proliant Microserver N40L

- HP Smart Array Controller P410/512 BBWC, FW 3.66

- 4 x 2TB as one Raid5

- HP-ESXi-5.5.0-iso-5.72A

I read a lot of articles about >2TB limitations of older ESXi versions or controllers, 4TB limitation of C# vSphere Client, old firmware and esxi driver problems, etc.

But I could not figure out the problem.

The P410 controller  shows 5.5TB:

~ # esxcli hpssacli cmd -q "controller slot=1 show config"

Smart Array P410 in Slot 1                (sn: PACCRID110510NR)

   array A (SATA, Unused Space: 0  MB)

      logicaldrive 1 (5.5 TB, RAID 5, OK)

      physicaldrive 2I:0:5 (port 2I:box 0:bay 5, SATA, 2 TB, OK)

      physicaldrive 2I:0:6 (port 2I:box 0:bay 6, SATA, 2 TB, OK)

      physicaldrive 2I:0:7 (port 2I:box 0:bay 7, SATA, 2 TB, OK)

      physicaldrive 2I:0:8 (port 2I:box 0:bay 8, SATA, 2 TB, OK)

   SEP (Vendor ID PMCSIERA, Model  SRC 8x6G) 250  (WWID: 5001438013D9F37F)

ESXi obviously recognises the same size:

~ # esxcli storage core device list

naa.600508b1001ca5e68adc0bc4bc508d6e

   Display Name: HP Serial Attached SCSI Disk (naa.600508b1001ca5e68adc0bc4bc508d6e)

   Has Settable Display Name: true

   Size: 5723091

   Device Type: Direct-Access

   Multipath Plugin: NMP

   Devfs Path: /vmfs/devices/disks/naa.600508b1001ca5e68adc0bc4bc508d6e

   Vendor: HP

   Model: LOGICAL VOLUME

   Revision: 3.66

   SCSI Level: 5

   (etc...)

But only offers 4TB:

~ # df -h

Filesystem   Size   Used Available Use% Mounted on

VMFS-5       3.6T   2.1T      1.5T  58% /vmfs/volumes/mainstorage

I tried to increase the datastore size, last used sector was 11720890367 and last offered sector was 11720890510 which does not really seem to result in an increase of 1.8TB.

Thanks for your help.
