Symptom

The NX-OS Compact Image Procedure may fail on Nexus 3000, 3100, and 3500 devices when reducing the file size of an NX-OS binary image file in the NX-OS 9.3(x) software train or higher. An example of this issue is shown below, where the NX-OS Compact Image Procedure has been invoked on the NX-OS 9.3(3) binary image file while copying the binary image file via SCP (Secure Copy Protocol): switch# copy scp://username@192.0.2.100/nxos.9.3.3.bin bootflash: compact vrf management Outbound-ReKey for 192.0.2.100:22 Inbound-ReKey for 192.0.2.100:22 username@192.0.2.100's password: nxos.9.3.3.bin 29% 477MB 4.9MB/s 03:49 ETA lost connection Scp Compact of /bootflash/nxos.9.3.3.bin failed Error doing scp

Conditions

This issue can be observed under the following conditions: 1. Issue is observed on a Nexus 3000 (3048, 3064, etc.), 3100 (3132, 3172, etc.), or 3500 (3548-10G, 3548-10GX, etc.) device. 2. Nexus device is running an NX-OS software release prior to 7.0(3)I7(7) (such as 7.0(3)I7(3), 7.0(3)I7(6), etc.) or 9.2(4) (such as 9.2(1), 9.2(3), etc.) 3. Attempting to reduce the file size of an NX-OS 9.3(x) software release binary image file through the NX-OS Compact Image Procedure via SCP (Secure Copy Protocol).

Workaround

Invoking the NX-OS Compact Image Procedure against an NX-OS software binary image file in the 9.3(x) train or higher (such as 9.3(1), 9.3(2), 9.3(3), etc.) is not supported until NX-OS software release 7.0(3)I7(7) or 9.2(4). In order to invoke the NX-OS Compact Image Procedure against an NX-OS software binary image file in the 9.3(x) train or higher, one must upgrade to NX-OS software release 7.0(3)I7(7) (or higher) or 9.2(4) (or higher).
