T4-4 server LDOM's and iSCSI

Hello all,
I have a setup like 2 x T4-4 server and 1x ZFS 7320 Storage with 10G Ethernet connectivity between these . Each T4 server i configured with 4 Ldom's in which the OS disk is the iSCSI lun allocated from ZFS storage.
Now i would like to know
1. is any known issues for allocating iSCSi luns as LDOM OS disk
2. which is the best way to allocate lun from ZFS 7320 to these LDOM's for filesystem ?
3. how can i allocate raw LUN for oracle ASM in the LDOM ? is ISCSI is a good option ? is any known issues ?
Thanks and regards
Anz

Windows Server 2012 - Hyper-V - iSCSI SAN - All Hyper-V Guests stops responding and extensive disk read/write

We have a problem with one of our deployments of Windows Server 2012 Hyper-V with a 2 node cluster connected to a iSCSI SAN.
Our setup:
Hosts - Both run Windows Server 2012 Standard and are clustered.
HP ProLiant G7, 24 GB RAM, 2 teamed NIC dedicated to Virtual Machines and Management, 2 teamed NIC dedicated to iSCSI storage. - This is the primary host and normaly all VMs run on this host.
HP ProLiant G5, 20 GB RAM, 1 NIC dedicated to Virtual Machines and Management, 2 teamed NIC dedicated to iSCSI storage. - This is the secondary host that and is intended to be used in case of failure of the primary host.
We have no antivirus on the hosts and the scheduled ShadowCopy (previous version of files) is switched of.
iSCSI SAN:
QNAP NAS TS-869 Pro, 8 INTEL SSDSA2CW160G3 160 GB i a RAID 5 with a Host Spare. 2 Teamed NIC.
Switch:
DLINK DGS-1210-16 - Both the network cards of the Hosts that are dedicated to the Storage and the Storage itself are connected to the same switch and nothing else is connected to this switch.
Virtual Machines:
3 Windows Server 2012 Standard - 1 DC, 1 FileServer, 1 Application Server.
1 Windows Server 2008 Standard Exchange Server.
All VMs are using dynamic disks (as recommended by Microsoft).
Updates
We have applied the most resent updates to the Hosts, WMs and iSCSI SAN about 3 weeks ago with no change in our problem and we continually update the setup.
Normal operation
Normally this setup works just fine and we see no real difference in speed in startup, file copy and processing speed in LoB applications of this setup compared to a single host with 2 10000 RPM Disks. Normal network speed is 10-200 Mbit, but occasionally
we see speeds up to 400 Mbit/s of combined read/write for instance during file repair
Our Problem
Our problem is that for some reason all of the VMs stops responding or responds very slowly and you can for instance not send CTRL-ALT-DEL to a VM in the Hyper-V console, or for instance start task manager when already logged in.
Symptoms (i.e. this happens, or does not happen, at the same time)
I we look at resource monitor on the host then we see that there is often an extensive read from a VHDX of one of the VMs (40-60 Mbyte/s) and a combined write speed to many files in \HarddiskVolume5\System Volume Information\{<someguid and no file extension>}.
See iamge below.
The combined network speed to the iSCSI SAN is about 500-600 Mbit/s.
When this happens it is usually during and after a VSS ShadowCopy backup, but has also happens during hours where no backup should be running (i.e. during daytime when the backup has finished hours ago according to the log files). There is however
not that extensive writes to the backup file that is created on an external hard drive and this does not seem to happen during all backups (we have manually checked a few times, but it is hard to say since this error does not seem leave any traces in event
viewer).
We cannot find any indication that the VMs themself detect any problem and we see no increase of errors (for example storage related errors) in the eventlog inside the VMs.
The QNAP uses about 50% processing Power on all cores.
We see no dropped packets on the switch.
(I have split the image to save horizontal space).
Unable to recreate the problem / find definitive trigger
We have not succeeded in recreating the problem manually by, for instance, running chkdsk or defrag in VM and Hosts, copy and remove large files to VMs, running CPU and Disk intensive operations inside a VM (for instance scan and repair a database file).
Questions
Why does all VMs stop responding and why is there such intensive Read/Writes to the iSCSI SAN?
Could it be anything in our setup that cannot handle all the read/write requests? For instance the iSCSI SAN, the hosts, etc?
What can we do about this? Should we use MultiPath IO instead of NIC teaming to the SAN, limit bandwith to the SAN, etc?

Hi,
> All VMs are using dynamic disks (as recommended by Microsoft).
If this is a testing environment, it’s okay, but if this a production environment, it’s not recommended. Fixed VHDs are recommended for production instead of dynamically expanding or differencing VHDs.
Hyper-V: Dynamic virtual hard disks are not recommended for virtual machines that run server workloads in a production environment

> This is the primary host and normaly all VMs run on this host.
According to your posting, we know that you have Cluster Shared Volumes in the Hyper-V cluster, but why not distribute your VMs into two Hyper-V hosts.
Use Cluster Shared Volumes in a Windows Server 2012 Failover Cluster
http://technet.microsoft.com/en-us/library/jj612868.aspx
> 2 teamed NIC dedicated to iSCSI storage.
Use Microsoft MultiPath IO (MPIO) to manage multiple paths to iSCSI storage. Microsoft does not support teaming on network adapters that are used to connect to iSCSI-based storage devices. (At least it’s not supported until Windows Server 2008 R2. Although
Windows Server 2012 has built-in network teaming feature, I don’t article which declare that Windows Server 2012 network teaming support iSCSI connection)
Understanding Requirements for Failover Clusters
http://technet.microsoft.com/en-us/library/cc771404.aspx
> I have seen using MPIO suggests using different subnets, is this a requirement for using MPIO
> or is this just a way to make sure that you do not run out of IP adressess?
What I found is: if it is possible, isolate the iSCSI and data networks that reside on the same switch infrastructure through the use of VLANs and separate subnets. Redundant network paths from the server to the storage system via MPIO will maximize availability
and performance. Of course you can set these two NICs in separate subnets, but I don’t think it is necessary.
> Why should it be better to not have dedicated wireing for iSCSI and Management?
It is recommended that the iSCSI SAN network be separated (logically or physically) from the data network workloads. This ‘best practice’ network configuration optimizes performance and reliability.
Check that and modify cluster configuration, monitor it and give us feedback for further troubleshooting.

Ask the Expert: Cisco UCS Troubleshooting Boot from SAN with FC and iSCSI

Welcome to this Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about Cisco UCS Troubleshooting Boot from SAN with FC and iSCSI with Vishal Mehta and Manuel Velasco.
The current industry trend is to use SAN (FC/FCoE/iSCSI) for booting operating systems instead of using local storage.
Boot from SAN offers many benefits, including:
Server without local storage can run cooler and use the extra space for other components.
Redeployment of servers caused by hardware failures becomes easier with boot from SAN servers.
SAN storage allows the administrator to use storage more efficiently.
Boot from SAN offers reliability because the user can access the boot disk through multiple paths, which protects the disk from being a single point of failure.
Cisco UCS takes away much of the complexity with its service profiles and associated boot policies to make boot from SAN deployment an easy task.
Vishal Mehta is a customer support engineer for Cisco’s Data Center Server Virtualization TAC team based in San Jose, California. He has been working in the TAC for the past three years with a primary focus on data center technologies such as Cisco Nexus 5000, Cisco UCS, Cisco Nexus 1000v, and virtualization. He has presented at Cisco Live in Orlando 2013 and will present at Cisco Live Milan 2014 (BRKCOM-3003, BRKDCT-3444, and LABDCT-2333).

Hello Evan
Thank you for asking this question. Most common TAC cases that we have seen on Boot-from-SAN failures are due to misconfiguration.
So our methodology is to verify configuration and troubleshoot from server to storage switches to storage array.
Before diving into troubleshooting, make sure there is clear understanding of this topology. This is very vital with any troubleshooting scenario. Know what devices you have and how they are connected, how many paths are connected, Switch/NPV mode and so on.
Always try to troubleshoot one path at a time and verify that the setup is in complaint with the SW/HW interop matrix tested by Cisco.
Step 1: Check at server
a. make sure to have uniform firmware version across all components of UCS
b. Verify if VSAN is created and FC uplinks are configured correctly. VSANs/FCoE-vlan should be unique per fabric
c. Verify at service profile level for configuration of vHBAs - vHBA per Fabric should have unique VSAN number
Note down the WWPN of your vhba. This will be needed in step 2 for zoning on the SAN switch and step 3 for LUN masking on the storage array.
d. verify if Boot Policy of the service profile is configured to Boot From SAN - the Boot Order and its parameters such as Lun ID and WWN are extremely important
e. finally at UCS CLI - verify the flogi of vHBAs (for NPV mode, command is (from nxos) – show npv flogi-table)
Step 2: Check at Storage Switch
a. Verify the mode (by default UCS is in FC end-host mode, so storage switch has to be in NPIV mode; unless UCS is in FC Switch mode)
b. Verify the switch port connecting to UCS is UP as an F-Port and is configured for correct VSAN
c. Check if both the initiator (Server) and the target (Storage) are logged into the fabric switch (command for MDS/N5k - show flogi database vsan X)
d. Once confirmed that initiator and target devices are logged into the fabric, query the name server to see if they have registered themselves correctly. (command - show fcns database vsan X)
e. Most important configuration to check on Storage Switch is the zoning
Zoning is basically access control for our initiator to targets. Most common design is to configure one zone per initiator and target.
Zoning will require you to configure a zone, put that zone into your current zonset, then ACTIVATE it. (command - show zoneset active vsan X)
Step 3: Check at Storage Array
When the Storage array logs into the SAN fabric, it queries the name server to see which devices it can communicate.
LUN masking is crucial step on Storage Array which gives particular host (server) access to specific LUN
Assuming that both the storage and initiator have FLOGI’d into the fabric and the zoning is correct (as per Step 1 & 2)
Following needs to be verified at Storage Array level
a. Are the wwpn of the initiators (vhba of the hosts) visible on the storage array?
b. If above is yes then Is LUN Masking applied?
c. What LUN number is presented to the host - this is the number that we see in Lun ID on the 'Boot Order' of Step 1
Below document has details and troubleshooting outputs:

Migrade old NW-cluster to VmWare and iSCSI

That's the job to be done,
question is just; which way to go;
Setup today is;
2x Single-CPU XeonServers, both connected
to 2xPromise 15HD/Raidkabinetts over 160mb SCSI.
This install beeing approx 5 years old and is getting slow and full.
Idea is to buy new, fast 6core Intel servers, run VmWare which makes
use of the power and make our life easier....
One question Im wondering about and have a guess regarding the answer
to is;
iSCSI based storage for these servers, should it be assigned and
supplied through VmWare or should the virtual NWserver running under
VmWare connect directly to the iSCSI storage ?
Usually, having an additional step on the way should be overhead, but
with regards to support for load-balancing NIC's, memory,etc,, my
guess is that the opposite could be true here; meaning that the VmWare
box should handle all storage and NW getting it's storage through
VmWare. But,, again just my guess...any input ?
Another question of course is Netware Vs Linux OES.
We have long time experience with NW and find our way around it well,
the Linux part is still something we really don't feel that at home
with. The install's of OES on Linux we've done for lab, test's etc
have allways felt rather unfinished. One could think that beeing from
the Novell/Netware camp, a logical step should be Linux/OES but
....Even when following the online doc's to do a basic test-setup works
quite ..bad...to much manual fixes getting stuff to work, to much
hazzle getting registration and updates to work....
Still, going virtual might be a way to make it easier switching to
OES/Linux since it'll be easier having a backup/image each time one
try do update,fix,,etc,,etc..
In the end, the needs are basic, one Groupwise server and one
FileServer. Going virtual enables us to over time migrate other
resources to....

Thanks 4 the quick reply Massimo,
Well, iSCSI or not, the other part of the question.
Time IS probably here to replace Netware, that much is obvious.
With the existing setup, we got working backups,
with our W2k/03/08, we got working backups and disaster recovery plans
Moving forward, using OES for us at least, seems a more difficult path
while any move from Netware today would probaby give us better
throughput. Using VmWare seems like a managable solution since do
updates/upgrades and backups could be done easily. To have a image to
revert to if any update goes wrong is much easier/faster than a
re-install each time....

Difference between using app server connection pooling and using the driver

Hi all,
How to get connection pooling with out application server and tomcat also?
What is the difference between using app server connection pooling and using the driver supported connection pooling?
Regards,
Murali

maybe the performance of App server pool is better than the JDBC pool,
for you don't know wether the implementation of the JDBC interface is good or bad.

I have a Windows 2003 Server 64-Bit, and when I upgraded to Firefox 4.0.1 now it won't run, it keeps saying to restart to complete the installation, but I've restarted theserver 4 times, and I still can't use it.

I have a Windows 2003 Server 64-Bit, and when I upgraded to Firefox 4.0.1 now it won't run, it keeps saying to restart the computer to complete the installation, but I've restarted theserver 4 times, and I still can't use it.

I ended up putting it in DFU mode. It's kinda hard to tell it was in DFU mode because nothing showed on the screen, it was just black, but the sounds from the computer helped to tell me it was connected.
Itunes still didn't recognize the device for whatever reason.
So I used redsn0w. I don't know if I can say that on these forums, but considering itunes was worthless at this point I am going to give credit where credit is due.
Now I am giving itunes a second chance to upgrade to 5.1, if it doesn't work, well, back to redsnow and maybe I will even jailbreak it this time rather than just using the fecovery fix found under extras.

Remote Desktop Gateway on Windows Server 2012 R2 and IPAD

Hi guys,
Would love some help with an issue I been struggling for a couple of days now.
I have a RDS 2012 R2 Gateway configured and it works great with all Windows clients both internal and external communication. The problems comes now when my I want to use IPAD
from APPLE. I installed latest RD Client from Microsoft and it works great from the internal network but as soon the device is moved to an external network the client get an error while connecting. Gateway is located in the domain network.
The error is “Failed to parse authorization Challenge”,
This is what I see in the log file from the RD Client.

Adam Bokiniec

Hi Jeremy,
I found a solution, thanks for you effort. The solutions is the following.
First thing that needs to be done is either solution from options below, I did the Solution 1 in my case and added a NPS server to AD. (https://blogs.technet.com/b/networking/archive/2010/01/14/remote-desktop-gateway-client-fails-authentication-with-your-user-account-is-not-authorized-to-access-the-rd-gateway.aspx)
Solution 1
Register the NPS server in Active Directory:
In Server Manager, browse to the following location: Roles\Network Policy and Access Services\NPS (Local).
Right click on the NPS (Local) node and choose Register server in Active Directory.
Click OK to authorize the server when prompted.
Solution 2
Open Active Directory Users and Computers on any Domain Controller of the same domain as the Remote Desktop Gateway.
Add the Computer Name of the Remote Desktop Gateway to the RAS and IAS Servers group.
Situation B
Restart the RDS host and Gateway server.
Secondly and the most important is to configure an alternate address that match your public certificate. My public certificate CNAME is “remote.domain.se”.
All commands need to be run as administrator in PowerShell
To show you current configuration run the following commands:
CollectionName is the Collection Name you created for the RDS deployment.
To get your collection name type
Get-RDSessionCollection
When you got the collection name type
Get-RDSessionCollectionConfiguration -CollectionName "RDS - Terminal Server" | FL *
The default configuration will look like this:
CustomRdpProperty     : use redirection server name:i:1
No to add you public domain name that match the certificate run the following command
Set-RDSessionCollectionConfiguration –CollectionName " RDS - Terminal Server " -CustomRdpProperty "use redirection server name:i:1 `n alternate full address:s:remote.domain.se
Run again to verify your settings
Get-RDSessionCollectionConfiguration -CollectionName "RDS - Terminal Server" | FL *
Now it show look something like this

My 4th generation iPod Touch won't let me get on to the App Store. When I log on to iTunes, an alert pops up that says the certificate for the server is invalid, and that it may be a server pretending to be iTunes. What should I do?

My iPod won't let me on to the App Store, and whenever I go on to ITunes, an alert pops up that the certificate for the server is invalid, and that I may be connecting to a server that is only pretending to be iTunes.apple.com and my personal info may be at risk. I downloaded an emulator yesterday from coolroms.com but deleted the app this afternoon. I cleared my safari search data, my cookies and data, and web inspector, which still didn't work. I then proceeded to reset my iPod and then download the newest version of IOS 6.1.5 but yet still am having problems. Also to the App Store and iTunes, several other apps aren't working. Any help here?

Also, when I go on to safari, another alert pops up that safari cannot verify the identity of the website, anything that I type in to as common as google.com. It gives me 3 options to either cancel, look at details, and continue. I've looked at the details of the website of Google and it is legitimate the site. Any help?

Single directory Server for Messaging and Portal

We are trying to unify our directory services.
At present, there two directory servers, one for iPlanet messaging 5.2 and another for Portal server 6.0.
Messaging's Directory server is v5.1 and Portal's Directory server is v5.2. Their BaseDN is same.
Now, What we are planning to do is as below.
1. LDIF everything from Msgr Directory and import into Portal's Directory.
2. Point Msg Server to the Portal's directory.
But, we are not sure what to export or how to tell messaging server to look at the Portal's Directory. Any help will be greatly appreciated!!!
Thanks

What you are trying to do is non-trivial.
Setting the ldap server for user and groups on the mail server is easy enough -- look at the output of configutil and you will find the values of local.ugldap*
define the values you need to change.
e.g.:
local.ugldapbasedn
local.ugldapbindcred
local.ugldapbinddn
local.ugldaphost
local.ugldapport
etc.
These are all listed in the messaging reference manual.
You need to ensure that the schemas of the two apps. match. For example, if you are using schema 1 for mail and schema 2 for the portal (quite likely), there will be a lot more work to do on the directory than simply moving the user entries accross and merging them.
Unless you have done this sort of thing before, or feel very comfortable and knowlegable about how the messaging server in partuicular works with LDAP, I would suggest that you seriously consider getting help from Sun Professonal Services.

Windows Server 2008 R2 and Windows 7 DNS Problem

Hi,
I have a DNS Server hosted in Windows Server 2008 R2 and our clients are using Windows 7. All are working fine then suddenly there are times that our client cannot access our internal site and cannot connect with our IM which is also hosted in the server.
Tried to ping the server's IP but got this result:
Ping request could not find host .com. Please check the name and
try again.
NSLookup works fine. Tried to use the ip address instead of the domain name and it works. Resetting network connection seems to resolve the issue but we cannot do it all the time especially when we have hundreds of computers in our office. Anyone have ideas
regarding this?

Hi,
“Resetting network connection seems to resolve the issue but we cannot do it all the time especially when we have hundreds of computers in our office. Anyone have ideas regarding
this?”
It seems is the client IP address conflict, it may cause by your DHCP Conflict Detection Attempts value setup is not appropriate. You can try to set Conflict Detection Attempts
to a value other than 0.

REMOTE DESKTOP SERVICES CLIENT ACCESS LICENSES FOR MICROSOFT WINDOWS SERVER 2012 STANDARD AND DATACENTER

I am using a window 7 professional service pack 1 and I purchase REMOTE DESKTOP SERVICES CLIENT ACCESS LICENSES FOR MICROSOFT WINDOWS SERVER 2012 STANDARD AND DATACENTER. but the seller did not send me any installation CD or instruction
on how to use it.
Please how can I use it on my window 7 professional service pack 1.
Thank you.

Though Bill is absolutely correct for most CALs, Remote Desktop Services does have its own special licensing server. I haven't installed one on 2012, yet, but here is a step-by-step guide for 2008.

Here is a lab guide for 2012 -
http://technet.microsoft.com/en-us/library/jj134160.aspx
But, the explanation of your environment begs the question - what are you trying to do? You say you have a desktop OS and you are talking about Windows Server products. In that light, your question does not make a lot of sense.

Welcome to the SQL Server Disaster Recovery and Availability Forum

(Edited 8/14/2009 to correct links - Paul)
Hello everyone and welcome to the SQL Server Disaster Recovery and Availability forum. The goal of this Forum is to offer a gathering place for SQL Server users to discuss:
Using backup and restore
Using DBCC, including interpreting output from CHECKDB and related commands
Diagnosing and recovering from hardware issues
Planning/executing a disaster recovery and/or high-availability strategy, including choosing technologies to use
The forum will have Microsoft experts in all these areas and so we should be able to answer any question. Hopefully everyone on the forum will contribute not only questions, but opinions and answers as well. I’m looking forward to seeing this becoming a vibrant forum.
This post has information to help you understand what questions to post here, and where to post questions about other technologies as well as some tips to help you find answers to your questions more quickly and how to ask a good question. See you in the group!

What to post in this forum
It seems obvious, but this forum is for discussion and questions around disaster recovery and availability using SQL Server. When you want to discuss something that is specific to those areas, this is the place to be. There are several other forums related to specific technologies you may be interested in, so if your question falls into one of these areas where there is a better batch of experts to answer your question, we’ll just move your post to that Forum so those experts can answer. Any alerts you set up will move with the post, so you’ll still get notification. Here are a few of the other forums that you might find interesting:

How to ask a good question
Make sure to give all the pertinent information that people will need to answer your question. Questions like “I got an IO error, any ideas?” or “What’s the best technology for me to use?” will likely go unanswered, or at best just result in a request for more information. Here are some ideas of what to include:
For the “I got an IO error, any ideas?” scenario:
The exact error message. (The SQL Errorlog and Windows Event Logs can be a rich source of information. See the section on error logs below.)
What were you doing when you got the error message?
When did this start happening?
Any troubleshooting you’ve already done. (e.g. “I’ve already checked all the firmware and it’s up-to-date” or "I've run SQLIOStress and everything looks OK" or "I ran DBCC CHECKDB and the output is <blah>")
Any unusual occurrences before the error occurred (e.g. someone tripped the power switch, a disk in a RAID5 array died)
If relevant, the output from ‘DBCC CHECKDB (yourdbname) WITH ALL_ERRORMSGS, NO_INFOMSGS’
The SQL Server version and service pack level
For the “What’s the best technology for me to use?” scenario:
What exactly are you trying to do? Enable local hardware redundancy? Geo-clustering? Instance-level failover? Minimize downtime during recovery from IO errors with a single-system?
What are the SLAs (Service Level Agreements) you must meet? (e.g. an uptime percentage requirement, a minimum data-loss in the event of a disaster requirement, a maximum downtime in the event of a disaster requirement)
What hardware restrictions do you have? (e.g. “I’m limited to a single system” or “I have several worldwide mirror sites but the size of the pipe between them is limited to X Mbps”)
What kind of workload does you application have? (or is it a mixture of applications consolidated on a single server, each with different SLAs) How much transaction log volume is generated?
What kind of regular maintenance does your workload demand that you perform (e.g. “the update pattern of my main table is such that fragmentation increases in the clustered index, slowing down the most common queries so there’s a need to perform some fragmentation removal regularly”)
Finding the Logs
You will often find more information about an error by looking in the Error and Event logs. There are two sets of logs that are interesting:
SQL Error Log: default location: C:\Program Files\Microsoft SQL Server\MSSQL.#\MSSQL\LOG (Note: The # changes depending on the ID number for the installed Instance. This is 1 for the first installation of SQL Server, but if you have mulitple instances, you will need to determine the ID number you’re working with. See the BOL for more information about Instance ID numbers.)
Windows Event Log: Go to the Event Viewer in the Administrative Tools section of the Start Menu. The System event log will show details of IO subsystem problems. The Application event log will show details of SQL Server problems.

hi,I have a question on sql database high availability. I have tried using database mirroring, where I am using sql standard edition, in this database mirroring of synchronous mode is the only option available, and it is giving problem, like sql time out errors on my applicatons since i had put in the database mirroring, as asynchronous is only available on enterprise version, is there any suggestions on this. thanks ---vijay

Windows 2008 Server boot loop and unable to log on in Safe mode

The Situation: I used msconfig to reboot Windows 2008 Server r2 into safe mode. On rebooting, boot progresses ok and the log in screen appears very quickly, then disappears and the machine reboots. I've tried typing the password very quickly and whether
I get it wrong or just can't get enough typed in time, I don't know, but the reboot loop continues. So, i can't log on and can't change safe boot back to normal.
I know Server 2008 uses bcdedit and no longer has a boot.ini, so I don't know if it is still possible manually to amend a boot file so it starts in normal mode again. Can anyone help me to break out of this boot loop without having to resort to anything
major, such as reinstallation?
Just to make clear, I haven't updated the system and the only change made was with msconfig to require safe boot on restarting.
Thanks

from the safemode try this syntax
Syntax: bcdedit /deletevalue {default} safeboot

How on earth is that a good answer? Sorry for the necrosis here of bringing up a post 9 months later, but I just ran in to this issue again. The OP said that he was STUCK IN A BOOT LOOP having placed himself in SAFEMODE already.
How is he supposed to type this in if he can't log in?
What worked for me was to keep striking F8 like a cobra during boot and telling it to use the Last Known Good Configuration option, after the 4th autoreboot, it let me log in and let me switch it back out of the safe mode and back to the normal boot. Yes,
I am aware this is quite lucky and now I don't have to rebuild all my server set up, and that your mileage may vary here, but, keep trying, you might be lucky.
