Out of Band management: iDRAC. For sure iDRAC will alarm with email if you have configure and activate it but IIRC the iDRAC7 doesnt include a "storage" section within its GUI. In Band: OpenManage Server Administrator(The webapp which listen on port 1311) or iDRAC tools aka "racadm" which is usefull when you have forget IP address and Password from your iDRAC. Note: Our nagios like monitoring system use the command line stuff which comes with OMSA and also SNMP. Regards,Joerg
Thats it. Theres so much time since I assembled this machine I cant remember how to check things in it w/o a reboot. How is that possible? I cant stop the services running in the VMs in this server but theres a long time since Ive checked the disks' health (2 disks in raid1) and details like CPU's temps...
How to check system's health (specially storage) w/o rebooting the server?
