Closed defect summary Solution When a host in a backbone fabric with a pair of Multiprotocol Extension blades, 1606 extension SAN switches, or a combination of the two is rebooted, it is unable to discover targets in the edge fabric due to timing window where a SID zone miss could drop a frame. If initiator does not retry PLOGI, it fails to discover targets in the edge fabric. Fixed in Fabric OS 6.4.0 Workaround prior to upgrade: Disable and then enable the target. NPIV tape devices may not be seen by hosts due to name server not sending subsequent PLOGI ACC following a sequence where NPIV device sends LOGO before link down. Fixed in Fabric OS 6.4.0 After upgrade to Fabric OS 6.x, rsh using user credential gets ifmodeshow eth0: ioctl (ETHTOOL_GSET) failed error in response to ifmodeshow command. Telnet and rsh with root credential work fine. Fixed in Fabric OS 6.4.0 Workaround prior to upgrade: Set suid permissions for ethmode: chmod +s /fabos/libexec/ ethmode.

Solution

Fixed in Fabric OS 6.4.0
Workaround prior to upgrade:
Disable and then enable the target.
When a host in a backbone fabric with a pair of Multiprotocol Extension
blades, 1606 extension SAN switches, or a combination of the two is
rebooted, it is unable to discover targets in the edge fabric due to timing
window where a SID zone miss could drop a frame. If initiator does
not retry PLOGI, it fails to discover targets in the edge fabric.
Fixed in Fabric OS 6.4.0
NPIV tape devices may not be seen by hosts due to name server not
sending subsequent PLOGI ACC following a sequence where NPIV
device sends LOGO before link down.
Fixed in Fabric OS 6.4.0
Workaround prior to upgrade:
Set suid permissions for ethmode:
chmod +s /fabos/libexec/
ethmode
.
After upgrade to Fabric OS 6.x, rsh using user credential gets
ifmod-
eshow eth0: ioctl (ETHTOOL_GSET) failed
error in response
to
ifmodeshow
command. Telnet and rsh with root credential work
fine.

HP StorageWorks Encryption SAN Switch or encryption blade drops
frames received from the host when the back-end tape becomes unre-
sponsive.
Fixed in Fabric OS 6.4.0
When an unsupported SFP is installed in an HP StorageWorks DC SAN
Director Multiprotocol Extension Blade, the amber LED flashes to indicate
a fault, as it should. However, if an optical cable is plugged into the
SFP, the amber LED extinguishes. The actual port status is unchanged.

command is issued.
