ESX OpenFiler iSCSI Basic Trouble Shooting Tips

Tags: , ,

This is not a VMware ESX iSCSI tutorial or technical guide that teach you how to configure VMware ESX and Openfiler iSCSI.

Basiclly this is a just a few trouble shooting tips regarding VMware ESX inside the VMware Workstation 6 and Openfiler iSCSI connection that what I'm looking for previously.

1. Check VMware ESX Log File and make sure no error:

   - /var/log/vmkernel

   - /var/log/vmkwarning

   - /var/log/message

2. VMware ESX Command:

   - esxcfg-swiscsi -e (Enables the software iSCSI initiator)

   - esxcfg-firewall -e swISCSIClient (Configures the ESX Service Console firewall (iptables) to allow the software iSCSI traffic)

   - vmkiscsi-tool -D -a 192.168.100.100 vmhba40 (Sets the target IP address for the vmhba40 adapter - software iSCSI initiator)

   - esxcfg-rescan vmhba40 (Rescans for storage devices on vmhba40.)

3. Networking:

   - Make sure you have Service Console & VMkernel(VMotion) sitting inside the same network subnet.

  

   - Make sure you can ping OpenFiler iSCSI IP address.

4. Hard Disk Space:

   - Make sure your VMware ESX root partition (/) is not empty.

5. Security:

   - Make sure you set iSCSI host access configuration for your volume to "ALLOW" in OpenFiler web administration page.

   - Make sure your have enter the correct CHAP password.

Hope this can help if you have any problem when connecting your VMware ESX and Openfiler iSCSI.
