The iSCSI boot does not work on RHEL7 with a static IP configured.

The iSCSI boot does not work on RHEL7 with a static IP configured.
from http://support.lenovo.com/gb/en/documents/ht100887


  1. Configure the iSCSI adapter and enable the boot from SAN feature.
  2. Enter the BIOS and change the boot mode to Legacy.
  3. Boot into the RHEL7.0 installation DVD and configure the NIC with a static IP address.
  4. Add a remote iSCSI target as a disk.
  5. Reboot after the installation completes and boot up will fail with the following error message:
[   2.375332] i8042: No controller found
[   2.592960] dracut: FATAL: For argument 'ip=::::localhost.localdomain:ens7:none'\nValue 'none' without static configuration does not make sense
[   2.593074] dracut: Refusing to continue
[   3.197719] System halted.

Workaround
iSCSI boot will succeed when adding the client IP address to the /boot/grub2/grub.cfg file.
Grub configuration files can be modified at the end of installation before rebooting.
To go to the shell and switch to the tty2 terminal (Ctrl-Alt-F2) or from the tmux screen on tty1, press Ctrl-B.  Then, change the configuration files of the installed system root mounted to /mnt/sysimage (eg /mnt/sysimage/boot/grub2/grub.cfg).
Example:
Before:
linux16 /vmlinuz-3.10.0-123.el7.x86_64 root=UUID=956c4dbb1-b287-42ba-94ec-f3c6b60c3361 ro vconsole.keymap=jp106 ip=::::localhost.localdomain:ens7:none... initrd16 /initramfs-3.10.0-123.el7.x86_64.img
After:
linux16 /vmlinuz-3.10.0-123.el7.x86_64 root=UUID=956c4dbb1-b287-42ba-94ec-f3c6b60c3361 ro vconsole.keymap=jp106 ip=192.168.122.10:::255.255.255.0:localhos... initrd16 /initramfs-3.10.0-123.el7.x86_64.img
Additional Information
This is a known issue of RHEL7.0.  This issue will be resolved in RHEL 7.1.

iSCSI CHAP

http://blog.csdn.net/sinchb/article/details/8433994#t10

1.What is CHAP?

Challenge-Handshake Authentication Protocol
iSCSI initiators and targets prove their identity to each other using the CHAP protocol, which includes a mechanism to prevent cleartext passwords from appearing on the wire.

2. iSCSI support two tpye chap authentication:

Initiator authentication和Target authentication

2.1 Initiator authentication

    When initiator(SUT) connect to target, initator should provide user name and password to target. The user name which initiator provdie is "incoming" account.
 Initiator authentication can  authentication independently, it call " Uni-directional Authentication",One way authentication

2.2 target authentication

    When initiator connect to target, target should provide user name and password to initiator. Tis is "outcoming" account

    target authentication have to authentication on both  initiator and target , it call " Bi-directional Authentication",Mutual  authentication
    iSCSI CHAP password length requirement must have 12~16 words

Migrating a virtual machine in vSphere 5.x fails with the error: The operation is not allowed in the current connection state of the host

Migrating a virtual machine in vSphere 5.x fails with the error: The operation is not allowed in the current connection state of the host


Symptoms

  • Cannot migrate a virtual machine in a vSphere 5.x environment.
  • Migrating a virtual machine fails with the error:

    Relocate virtual machine
    The operation is not allowed in the current connection state of the host
    Time: xx/xx/xxxx xx:xx:xx
    Target: xxxxx
    vCenter Server: xxxxx
  • The Summary tab of the powered on virtual machine reports this information:

    • CPU Usage - 0 MHz
    • Memory Usage - 0.00 MB

Resolution

To resolve this issue, perform these steps, verifying if the issue is resolved after each step:
  1. Restart the VMware VirtualCenter Server Service.
  2. Restart the Management agents on the ESX host running the virtual machine. For more information, see Restarting the Management agents on an ESXi or ESX host (1003490).
  3. Disconnect and reconnect the ESX host that is running the virtual machine to force vCenter Server to retrieve an updated set of data relating to the objects registered to the host.

VM with Windows 2008/2012 fail to power on when setup Intel X520/X540 SRIOV NIC

VM with Windows 2008/2012 fail to power on when setup Intel X520/X540 SRIOV NIC 

Details

ESXi supports a maximum of 31 vectors per PCI device.  If you add Intel Ethernet Server Adapter X520-SR2 (ixgbe), Intel Ethernet Server Adapter X540-SR2 as Direct I/O PCI devices to virtual machines with Windows 2008 and later guests, you cannot power on the virtual machines. When you start the virtual machine, Windows accesses all the message signaled interrupts (MSI/MSIX). When a device requests to support more than 31 interrupt vectors, the virtual machine stops responding and the vmware.log file reports an out of MSI-X vectors message.

This issue also occurs when you install the Windows PF driver for these adapters. You see an error similar to PCIPassthru: 07:00.1 tried to modify MSI-X vectors number 32-32, but maximum supported vector number is 31. During load time, the X520-2 device is marked as unsafe. The driver does not load what appears to be an unsafe device. The virtual machine starts and shows the error message.

Solution

To resolve this issue, expose fewer vectors to the guest operating system by adding the pciPassthru0.maxMSIXvectors = 31parameter to the virtual machine's configuration file.

From the vSphere Web Client

  1. Right-click the virtual machine and select Edit Settings.
  2. Click the Options tab and click General.
  3. Click Configuration.
  4. Click Add Row.
  5. Add the parameter to the new row:
    • In the Name column, add pciPassthru0.maxMSIXvectors.
    • In the Value column, add 31.
  6. Click OK.
From a command line

Note: Do not reinstall the driver before modifying the .vmx file.

  1. Open the .vmx file for the virtual machine in a text editor.
  2. Add this entry to the file:

    pciPassthru0.maxMSIXvectors = 31
  3. Reinstall the driver in the virtual machine.
Note: If multiple devices are present, ensure to add entries for each PCI device.

     pciPassthru0.maxMSIXvectors = xx, pciPassthru1.maxMSIXvectors = xx
