Using Dell DRAC with ssh

News No Comments »

One can manage Dell server with DRAC ( Dell Remote Access Controller ) via ssh session. iDRAC6 is little bit different than version 5. Here are the commands to access console and reboot / shutdown the server.

Connect:


$ ssh 192.168.1.19 -l root
root@192.168.1.19's password:
/admin1->

Access the console:


/admin1-> console com2

With DRAC5 one had to type:


Dell Remote Access Controller 5 (DRAC 5)
Firmware Version 1.20 (Build 07.03.02)

$ connect com2

To reboot the server type reset:


/admin1-> cd /system1
/admin1/system1
/admin1/system1-> reset

stop stands for poweroff and start for powerup.

In DRAC5 to use power functions one must first start SM CLP:


$ smclp
DRAC5 SM-CLP System Management Shell, version 1.0

I noticed that people end up this site with pattern “ssh reset drac”. If you are wondering how that is done, here it is:

ssh root@drac-ip
racadm racreset

This will reboot the DRAC if the web manage etc has crashed.

Notes for upgrading from OpenSolaris to Oracle Solaris express 11

Solaris And ZFS No Comments »

I had to upgrade OpenSolaris svn132 to new Oracle Solaris 11 express and this is what i learned.

iSCSI
We use comstar iscsi target which is also in solaris 11. First backup its configurations:


# svccfg export -a stmf > COMSTAR.backup

Bring all initiators offline and export zfs pools. If you get error that zpool is in use, you can delete luns with sbdadm delete-lu GUID ( dont worry, they will be imported later )

Now when you have freshly installed Solaris 11 express, export all the pools and restore the comstar backup:


# svccfg import COMSTAR.backup

Import luns with sbdadm import-lu /dev/zvol/rdsk/zpool/share and verify that the luns are up. After this enable stmf and verify that the target groups are restored from backup with stmfadm list-tg.

If everything is in place, you can start iscsi/target.
