when i upgrade the call manager from 7.1.3 to 7.1.5 i got this error "An unknown error occurred while accessing the upgrade file"
this error apear at the end of instlaation , i dont think it is from the disk that contain the upgrae file, i burned alot of cds and with difrrent version but i got the same result
i think the error accored at this point :
"CCMInstall|cmdExec: Command: /partB/usr/local/bin/base_scripts/env.sh nice -n 19 /usr/sbin/chroot /partB /usr/local/cm/script/188.8.131.5200-12/cm-dbl-install L2 PostInstall 184.108.40.20600-12 220.127.116.11000-1 /usr/local/cm/ /partB/usr/local/cm/ /common/log/install/capture.txt -- failed with failure code 1|<LVL::Warn>"
if any body know how i can know which entry of the DP have this error please tell me.
i attached the instllation log file with the email
i used RTMT to monitor the update and to figure which entry in the DB exactly that cause the error but it didint work i coud'nt understand it.
now i have a question if i deleted all my DB (all the phones and the devices in the pub & sub) will it work or not ?
is the errore related with this message in the log:
ServerApiManager||Method: getHardwareAttribute args: HWModel|- current mode=HSSI_Mode completed with code 
is the code 0 mean the update is not for this server?
