Hello,
We have 2 Dell R320 boxes with ESX 5.5 without disks, the systems boot from the dual SD cards fine and last week I found this article on Dell website:
Configuring iDRAC vFlash as a VMware ESXi VMKernel Coredump Collector - White Papers - TechCenter E...
Since we have the iDrac7 with its own 8GB SD card, I thought that is a good idea to configure the LOG and COREDUMP onto.
What this basically show us in that article is to turn the USBarbitrator off permanently and to create a partition on the iDrac SD card, which shows up as a disk in ESXi.
It worked fine until I rebooted a host.
After reboot the LOG partition still works fine, but the COREDUMP partition is gone according to ESXi 5.5.
Also vCenter complains for this host that the coredump target has not been configured.
SSH into the box and checked the coredump partition is still there:
~ # fdisk /dev/disks/mpx.vmhba33\:C0\:T0\:L1 -l
***
*** The fdisk command is deprecated: fdisk does not handle GPT partitions. Please use partedUtil
***
Disk /dev/disks/mpx.vmhba33:C0:T0:L1: 838 MB, 838860800 bytes
128 heads, 1 sectors/track, 12800 cylinders
Units = cylinders of 128 * 512 = 65536 bytes
Device Boot Start End Blocks Id System
/dev/disks/mpx.vmhba33:C0:T0:L1p1 1 12800 819199+ fc VMKcore
Even the partition type is correct (fc).
But then I do the coredump partition list, which normally showed this partition, now it's gone:
~ # esxcli system coredump partition list
no configured dump partition found; skipping
Been searching and looking, any ideas?
Thanks, Edwin
