)Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.0(1a)
OL-21012-01
Caveats
Symptom: The zone server fails the zone check for the host and virtual target with iSAPI, and then
rejects the host’s PLOGI request. This happens because of the two-second delay between the PLOGI
sent from host to the target, and because of the host port online RSCN. The issue also happens when
a host goes down and comes back after a zone set activation.This issue only occurs when hosts are
connected to a McData switch.
Workaround: This issue is resolved.
• CSCtc33466
Symptom: Following a successful IVR zone merge between two Cisco MDS fabrics, where each
fabric already had an active local IVR VSAN topology with an active IVR zone set, a new active
zone set with a concatenated IVR zone set was created, as well as two IVR zone sets in the full zone
set. However, when the ivr copy active-zoneset full-zoneset command was entered, the full IVR
zone set was not overwritten.
This symptom can occur if the zone ID or zone name of active zone set database and full zone set
database are the same. In such cases, the copy operation will not occur.
Workaround: This issue is resolved.
• CSCtc62666
Symptom: Write operations to the bootflash: file system on an MDS 9124 switch fail because the
bootflash: file system is read only. This issue only occurs on MDS 9124 systems released in 2009.
You can confirm this issue as follows:
– Check the console bootup logs for the following message:
Checking all filesystems....r.ERROR: bootflash: has unrecoverable error; please do
"format bootflash:"
– Check for syslog messages such as:
%KERN-2-SYSTEM_MSG: EXT3-fs error (device hda4): ext3_readdir: bad entry in
directory #11:
rec_len %% 4 != 0 - offset=0, inode=4294967295, rec_len=65535, name_len=255 - kernel
%KERN-2-SYSTEM_MSG: Remounting filesystem read-only -kernel
– When you try to write to the bootflash: file system, look for errors such as:
switch# copy tftp://1.2.3.4/testfile bootflash:
/bin/copy: cannot create regular file `/bootflash/testfile': Read-only file system.
Workaround: This issue is resolved.
• CSCtc68983
Symptom: Following an upgrade from SAN-OS Release 3.0(2a) to Release 3.3(2) on a switch with
IVR1 in non-NAT mode, IVR zone set activation does not go through successfully. An error message
like the following was displayed:
2009 Oct 9 18:23:56 <switchname> %IVR-2-CFS_PEER_LOST_WITHIN_SESSION: CFS peer with
switch wwn 20:00:00:0d:ec:27:92:c0 was lost in the middle of an active CFS session.
Abort the CFS session and re-enter the configuration changes
The IVR_DU database had a missing entry for the device which caused it to be stuck in advertising
state.
Workaround: This issue is resolved.
