Hi Dmitry,
You can see this error when combining the 2 files and not following
the naming conventions;
Procedure
Step 1 Ensure that you have completed the "Installing the Unrestricted COP File" section.
Step 2 From the Software Download page on Cisco.com, download the two UCSInstall files.
Step 3 To combine the two files, execute one of the following commands.
Note Because the UCSInstall_UCOS_UNRST_7.1.5.31900-3 build specifies a nonbootable ISO, the build proves useful only for upgrades. You cannot use this build for new installations.
a. If you have a Unix/Linux system, copy and paste the following command into the CLI:
cat UCSInstall_UCOS_UNRST_7.1.5.31900-3.sgn.iso_part1of2 UCSInstall_UCOS_UNRST_7.1.5.31900-3.sgn.iso_part2of2 > UCSInstall_UCOS_UNRST_7.1.5.31900-3.sgn.iso |
b. If you have a Windows system, copy and paste the following command into the command prompt (cmd.exe):
COPY /B UCSInstall_UCOS_UNRST_7.1.5.31900-3.sgn.iso_part1of2+UCSInstall_UCOS_UNRST_7.1.5.31900-3.sgn.iso_part2of2 UCSInstall_UCOS_UNRST_7.1.5.31900-3.sgn.iso |
Step 4 Use an md5sum utility to verify that the MD5 sum of the final file is correct.
for the Unrestriced version:
•UCSInstall_UCOS_UNRST_7.1.5.31900-3.sgn.iso_part1of2
•UCSInstall_UCOS_UNRST_7.1.5.31900-3.sgn.iso_part2of2
The MD5 for the Unrestricted combined download is: 4b53a2b676f9db562c4064a2cbc32095
