Dell iDrac – Fixing SSL Problem

2 Comments

Hi,

i got two Dell R710 servers which have the problem, that if you wanna open the iDrac web interface, google chrome gives you the error:

ERR_SSL_SERVER_CERT_BAD_FORMAT

its not the usual “hey you got a self signed certificate, its not cool, but you can pass” error ;D this error wont let you open the website.

You can fix this by the following steps:

  • Open a ssh connection to the corresponding iDrac (use the same password as for the webinterface)

ssh root@idrac-ip

  • Regenerate the certifcate

/admin1-> racadm sslresetcfg
Certificate regenerated successfully and webserver restarted

  • Reset the iDrac

/admin1-> racadm racreset soft
RAC reset operation initiated successfully. It may take up to a minute
for the RAC to come back online again.

 

and youre done!

Dell MD3220 – reset preferred controller module

Leave a comment

Recently, id resetted the controller modules of the Dell MD3220 Storage Array while troubleshooting some strange events (it didnt change anything, ok its not a windows system ;D ).

After this, the virtual disks changed their path to the second controller. Ok, its not “mission critical”, but you always get the message that the virtual disks are not one the preferred path.

So, as described in my last post, this is also one of the operations that cant be made with MD Storage Manager.

This command will help: smcli.exe your-md-dns-name-or-ip -c "reset storageArray virtualDiskDistribution;"

Ps: Here you can find the Command Line Guide for SMCLI:

Dell MD3220 – how to reset unreadable Sectors statistic

Leave a comment

Hy,

recently, i had the problem that our Dell MD3220 Storage Array was showing Alerts regarding unreadable sectors on disk drives.
Stupidly it didnt say which disk is affected. I thought that this is a old message, which is not cleared.

So my first step was resetting the statistic. If there are really defective sectors, the message will show up again.

The trick is, you cant do this over the gui (Dell MD Storage Manager) – you have to use SMCLI (which is part of the installation of the storage manager).

Here is the command:

scmli.exe your-md-dns-name-or-ip -c "clear allVirtualDisks unreadableSectors;"

The message is gone in my case.
