After updating a Solaris 11.0 installation to Solaris 11.1 with pkg update – none of servers iSCSI -targets were accessible. Under Windows disk management partition would show up as RAW -partition, data could still be rescued with recovery -software.

After troubleshooting it came clear that i’m not the only one.

Problem is in ImmediateData, and it seems to be resolved in the latest Solaris 11.1 -update (0.175.1.3.0.4.0) – which requires a support contract with Oracle to be downloaded….

 

If you don’t have access to Oracle Solaris Support -repository – stay in 11.0 until next major update is released, or use a workaround which disables ImmediateData:

Windows (tested):
1. Set the following registry value to 0:
HKLM\SYSTEM\CurrentControlSet\Control\Class{4D36E97B-E325-11CE-BFC1-08002BE10318}\<Instance Number>\Parameters\ImmediateData
2. Reboot

Linux (tested):
1. Disable ImmediateData in iscsid.conf (location depends on distro) or use the same iscsiadm -command as in Solaris
2. Restart the iSCSI service

Solaris (untested):
1. Disable ImmediateData:
# iscsiadm -m node -T ${IQN} -p ${IP}:${PORT},${TPGT} -o update -n node.session.iscsi.ImmediateData -v No
2. Restart the iSCSI service:
# svcadm restart svc:/network/iscsi/initiator:default

ESXi (untested):
1. Backup vmkiscsid.db
2. Edit vmkiscsid.db with sqlite3:
select * from nodes; update nodes set ‘<immediatedatakey>’ = ‘No’
3. Replace vmkiscsid.db with modified version (if you didn’t edit it in place) and reboot server

Debian Squeeze was released 06.02.2011.
Please note that Wheezy is still in testing -stage.  Debian Wheezy was released 04.05.2013

Just some quick steps how to do the upgrade (on your own risk).

Update Squeeze

aptitude update
aptidude upgrade
  1. Copy /etc/apt/sources.list to /etc/apt/sources.list.d/debian-wheezy.list and replace squeeze with wheezy. Or copy them inside sources.list. Use whatever mirror which is closest to you.
    deb http://ftp.fi.debian.org/debian/ wheezy main contrib non-free
    deb http://ftp.fi.debian.org/debian/ wheezy-updates main contrib non-free
    deb http://security.debian.org/ wheezy/updates main contrib non-free
  2. Update repository
    aptitude update
  3. Upgrade critical parts first – it will complain about libept1 – just let it be removed.
    aptitude install dpkg apt aptitude
  4. (Dist-)upgrade rest
    aptitude upgrade
    aptitude dist-upgrade
  5.  IF YOU ARE STILL RUNNING UNDER XEN3.x:
    Replace grub2 with grub1 (or just keep your old menu.lst at /boot/grub/)

    aptitude purge grub-pc
    aptitude install grub-legacy
  6. Always check that /boot/grub/menu.lst or /boot/grub/grub.cfg exists and defaults to right kernel
  7. Reboot and hope for the best

Debian 7.0(beta4) and i845G/GL didn’t work out-of-the box for me, X crashed without a log as soon as it tried to initialize.

After adding following to /usr/share/X11/xorg.conf.d/05-i845g.conf – everything seems to work:

<code>

Section “Device”
Option    “DRI”    “True”
Option    “Shadow”    “True”
Option    “XvMC”    “False”
Option    “XvPreferOverlay”    “False”
Identifier    “Card0”
Driver    “intel”
VendorName    “Intel Corporation”
BoardName    “82845G/GL [Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)
BusID    “PCI:0:2:0”
EndSection

</code>

It’s possible that this is fixed when Wheezy is officially released, at least a bug has been reported.
