Hi,

You need at least 80 GB to install CM 6.


Which version of CM are you trying to install?

Hi,

you need to need to put two disk of 80GB or more size. When Callmanager setup starts itself configures raid level, you don't need to configure anything related RAID.


Could you try to configure an array of 4 disk (2x72.5=145GB+2x72.5=145GB)?

4 disk with raid5 is ok from the beginning itself..

-tried removing 1disk after the successful installation with 4 disk and it was still ok..


so it looks like the install script is looking for a 4 disk on an dl380g4..


could anyone confirm this?

Hi,

the CCM setup trying to match your server to a MCX 78xx server (depending memory installed, harddisks installed and processor type there are several MCS different server). An DL380 can be a 7835 or 7845 depending how many harddisk and how many memory have you installed. So if you don't install 2 more harddisks, the CCM installer cannot continue with the installation.


I hope that you have a clearer sight of your problem.


Regards

Hi,

because your server model in Cisco terminology is equals a MCS 7845 (4 disks installed out of the box) and CCM setup waits that that your has installed four disk instead of 2 or 3. As I tell you before, if you don't install 4 disks, ccm setup cannot continue, because it is waiting for 4 disks.


Could you tell me your server specs?

not sure, but maybe your hardware detection sees the server as a MCS7845 instead of a 7835, maybe you have too many CPU's ?

have a look here;

If hw detect thinks it's a 7845 it wants to see 4 disks to make 2 arrays I believe
