=== USB / SD Hypervisor Checks === | |||
USB and SD cards are notorious for causing problems. Especially USB sticks, which were designed for occasional access storage, and not to be repetitively used in the fashion they are when running ESXi hypervisor. The SD cards may well be tarnished with the shadow of USB. In order to perform a disk check, use the following... | |||
'''Assumes your running ESXi4, if using ESXi3 use this procedure (from which this section is adapted from): http://www.vm-help.com/esx/esx3i/check_system_partitions.php''' | |||
Firstly a quick overview of the partitions... | |||
/vmfs/volumes/Hypervisor1 /bootbank Where the ESX boots from | |||
/vmfs/volumes/Hypervisor2 /altbootbank Used during ESX updates | |||
/vmfs/volumes/Hypervisor3 /store VMTools ISO's etc | |||
Everything else in an ESXi server is stored on the scratch disk, or is created at boot in a ramdisk | |||
Run <code> fdisk -l </code> to list the available partitions on the USB/SD card (you'll also see your SAN partitions as well).. | |||

to perform a verification pass use -V, or to test for bad sectors use -t (with which you also need to include -a (automatically repair) or -r (interactively repair) options). | |||
