The following partitions are created on the boot disk of ESXi.
||Alternate Boot Bank
||Coredump. Not used since ESXi 5.5. It exists for backward compatibility
||Coredump. Introduced in ESXi 5.5, required for hosts with huge RAM
||Store. Used for storing VMware tools etc..
||Scratch. Persistent storage for log files, not created on USB and SD card installation
||VMFS, local datastore. Not created on USB and SD card installation
Get partition table of the disk where ESXi is installed:
esxcli storage core device partition list
partedUtil getptbl /vmfs/devices/disks/ESXi_install_disk
The size of a partition is (End Sector – Start Secore) * 512 bytes.
Check active coredump partition:
esxcli system coredump partition list
Get a list of mounted filesystems. The boot partition and coredump partitions will not be mounted.
Up/Down Arrow: Everyone probably knows this
Page Up: Recalls first command
Page Down: Recalls latest command
F7: Shows command history like a text based menu
doskey /history: Prints command history
doskey /listsize=0: Clears command history
… and more.
I can’t remember them all except the ones I use on a daily basis.
Chris Wahl said it short and best:
Dedicate – the IPMI port is used exclusively for out of band access
Share – the on-board NIC’s first port is used exclusively for out of band access
Failover – try to use the IPMI port, and if it is not connected, fail over to the on-board NIC port
* The default setting is Failover, which will allow IPMI to be connected from either
the shared LAN port (LAN1/0) or the dedicated IPMI LAN port. Precedence is
given to the Dedicated LAN port over the shared LAN port.
* Select Dedicate for IPMI to connect through the IPMI Dedicated LAN port
at all time.
* Select Share for IPMI to connect through the LAN port on the board
Longer with more detail.
Check the current mode:
ipmitool raw 0x30 0x70 0x0c 0
The output will be one of these:
0x00 = Dedicated
0x01 = Onboard / Shared
0x02 = Failover
To set the mode to
ipmitool raw 0x30 0x70 0xc 1 1 0
ipmitool raw 0x30 0x70 0xc 1 1 1
ipmitool raw 0x30 0x70 0xc 1 0 0
In a Windows Server 2012 failover cluster environment, you cannot add a server that has the Active Directory Domain Services (AD DS) role as a node.
