IP Multipath groups can be configured to permit fail-over of IP addresses from one IP interface to another when either (a) a physical network device transitions to link-down, or (b) when an external network switch or path is no longer working. In the first software release, both of these failure mechanisms are always configured for IPMP groups. External path failure detection is performed by sending ICMP probes to neighboring addresses or gateway addresses. As a result, if network load and the network environment is such that ICMP probes are dropped, this may trigger an IPMP group fail-over even when the network is still servicing some traffic. To work-around this problem if it is a fundamental behavior of your network environment and load, go to Configuration/Services/IPMP and simply tune the ICMP probe error interval to an extremely high value such as 36000000 (ten hours).

The Configuration/Network view permits a wide variety of networking configuration changes on the Sun Storage system. One such change is taking an existing network interface and associating it with a different network datalink, effectively moving the interface's IP addresses to a different physical link (or links, in the case of an aggregation). In this scenario, the network routes associated with the original interface are automatically deleted, and must be re-added by the administrator to the new interface. In some situations this may imply loss of a path to particular hosts until those routes are restored.

The Configuration/Network view permits a wide variety of networking configuration changes on the Sun Storage system. One such change is modifying or deleting the active administrative interface over which the administrator is connected to the web browser or command-line interface itself, which may also be providing the default route for the system. The appliance software attempts to detect such modifications and warn the administrator first. If such a reconfiguration is confirmed or not detected in advance, the administrator will lose contact with the appliance during the network reconfiguration. The network reconfiguration will complete, but if contact cannot be restored with the appliance (by reloading the web address or reconnecting using ssh) due to an error in the configuration applied by the administrator or the loss of the default route, the administrator should log in using the service processor console and correct the configuration using the command-line.

|| {color:#000000}{*}Title{*}{color} | J4400 Emits Audible Alarm When a Drive is Hot-Unplugged ||
|| {color:#000000}{*}Platforms{*}{color} | 7410 ||
|| {color:#000000}{*}Related Bug IDs{*}{color} | 6725548 ||
In the current version of J4400 Array firmware, used in the disk enclosures for the Sun Storage 7410, the J4400 emits an audible alarm when a disk drive is hot-unplugged. The alarm warns the operator that a drive has been removed, and the alarm is silenced when the drive is replaced, either by the original drive or by a new replacement. In some operator scenarios, it may be preferable to not emit such an alarm, particularly if a spare drive is not immediately available. The operator can manually silence the alarm by depressing a button on the J4400 front panel. Future versions of the J4400 firmware and appliance software will disable this behavior and/or permit it to be configured by the administrator.

|| {color:#000000}{*}Platforms{*}{color} | All ||
|| {color:#000000}{*}Related Bug IDs{*}{color} | 6758825 ||
The Sun Storage products permit administrators to manage collections of *shares* and LUNs, grouped together into named *projects{*}that have common settings. NDMP backup applications operate on mounted filesystems and do not intrinsically understand Sun ZFS metadata and the relationship between projects and shares. In the current release of the Sun Storage 7x10 products, NDMP backup applications should be configured to backup individual shares of interest, and should not be directed to backup or restore the base mountpoint associated with an entire project. These settings will insure that individual shares are backed up and restored with all of their associated independent metadata.

If the appliance that is providing service fails, the other will complete the rejoin in its absence and take over. The only case in which availability may be impaired is if the bug is encountered following a loss of power to both appliance heads. In this case, service will not be restored until one of them is rebooted.
