Non-Disruptive Upgrade why is disruptive upgrade MDS9124 o my god!

Last DAY i have needed upgrade my MDS9124 from 5.0.4(d) to 5.2.8(e).

When i started the upgrade i recaived this message:

disruptive upgrade

O my god!!!! is not possible.

I found the solution… i have resolved with reload the switch (this is siwtch is up from 5 years and the memory is 90% busy).

After reload the upgrade is Non-disruptive

Non-Disruptive Upgrade why is disruptive upgrade MDS9124 o my god!


I need upgrade switch mds9124 for compatibility with San Volume Controller 7.4
Now  NX-OS on MDS switch is :

  kickstart: version 5.0(4d)
  system:    version 5.0(4d)

Command for view NX-OS is “show ver”

After this i have checked free space on bootflash dir:

dir bootflash:

In this switch i have less free space. I need old version.

MDS-CP-02# del bootflash:m9100-s2ek9-kickstart-mz.4.2.5.bin
MDS-CP-02# del bootflash:m9100-s2ek9-mz.4.2.5.bin

Ok i am ready to load news fw in to bootflash dir i use tftp server:
copy tftp:// bootflash:m9100-s2ek9-kickstart-mz.5.2.8e.bin
copy tftp://10.x.x.x/m9100-s2ek9-mz.5.2.8e.bin bootflash:m9100-s2ek9-mz.5.2.8e.bin


Backup configuration MDS Cisco Switch FC

I use tftp server.
Use command line, connect with ssh client to MDS switch. In this case MDS9124.

MDS-TAPE-3S-01# copy running-config tftp:
Enter destination filename: [MDS-TAPE-3S-01-running-config]
Enter hostname for the tftp server:
Trying to connect to tftp server……
Connection to server Established. Copying Started…..
