FDDI/9000 EISA Adapter Release Notes Compatibility Information and Installation Requirements Compatibility Information and Installation Requirements Software Requirements • HP-UX 10.20 operating system. If you are currently running HP-UX 9.x, you must upgrade to HP-UX 10.01, then to 10.20 before installing the FDDI/9000 EISA software version B.10.20.03, or later.
FDDI/9000 EISA Adapter Release Notes Compatibility Information and Installation Requirements NOTE If you install the FDDI/9000 EISA Adapter (hardware) before the software, the system will display the following error: “Warning: one or more EISA cards could not be configured.” Ignore this message. When you install the software, you will resolve this problem. If you have an earlier version of FDDI/9000 EISA, you must do the following: 1. Remove all FDDI EISA patches. 2. Install this version (B.10.20.11).
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.10.20.11 Patches and Fixes in Version B.10.20.11 The following patches have been incorporated into this version of the FDDI/9000 EISA software: • PHNE_18869 • PHNE_17285 • PHNE_17061 • PHNE_15665 Details regarding these patches and/or fixes follow: Table 1-1 PHNE_18869 Symptom Defect 1. The system panics with an instruction page fault with promiscuous mode enabled on the EISA FDDI interface. 1.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.10.20.11 Table 1-1 PHNE_18869 (Continued) Symptom Defect 4. The EISA FDDI driver does not report any errors when an invalid multicast address is added by a user. 4. All FDDI multicast addresses have the I/G (Individual/Group) bit set to 1. The driver code was not checking for attempts to add multicast addresses with the I/G bit 0, and would return success. 5. EISA FDDI nettl log messages do not appear after a card reset. 5.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.10.20.11 Table 1-1 Table 1-2 PHNE_18869 (Continued) Symptom Defect 8. Data page fault panic in fdi0_open. 8. The panic was happening when the EISA FDDI device file was opened, with no EISA FDDI card configured on the system. Under these circumstances, the open routing tries to access a null board structure pointer, resulting in a data page fault panic. PHNE_17285 Symptom Defect 1.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.10.20.11 Table 1-2 PHNE_17285 Symptom Defect 3. netstat(1M) used with the -i option shows a large number of inbound errors on the EISA FDDI interface. 3. Packets which were being dropped, either due to the interface being configured down (using the ifconfig(1M) command), or due to the driver not being able to decipher the protocol type of the packet, were counted as inbound errors for IP. 4.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.10.20.11 Table 1-2 Table 1-3 PHNE_17285 Symptom Defect 7. The ‘Operation Status’ of the EISA FDDI interface, as displayed by the lanadmin(1M) command, is not marked ‘down’ when there is a cable disconnect. 7. The ifOper MIB variable, that is displayed as the ‘Operation Status’ by the lanadmin(1M) command, shows the operational state of the interface.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.10.20.11 Table 1-3 PHNE_17061 (Continued) Symptom Defect 3. High checksum errors and degraded network performance, observed over EISA FDDI interface, on B and d class systems which are non-cache coherent I/O (that is, CCIO). 3. On systems without CCIO support, the driver needs to maintain cache coherency during DMA transactions, by flushing/purging the CPU cache as necessary.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.10.20.11 Table 1-3 Table 1-4 PHNE_17061 (Continued) Symptom Defect 6. System crashes, with either an HPMC or a memory protection fault panic, under high network traffic over the EISA FDDI interface. 6. Under heavy network traffic conditions, the EISA FDDI driver may sometimes invoke internal card resets to recover from transmit hangs.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.10.20.11 Table 1-4 PHNE_15665 Symptom Defect 2. When an attempt is made to change the MAC address of the card using lanadmin(1M), the link becomes unusable for up to 10 seconds and the MAC address remains unchanged. 2, The MAC address of the card cannot be changed. Users were not prevented from attempting to do this. 3.
FDDI/9000 EISA Adapter Release Notes What’s in Version B.11.00.07 What’s in Version B.11.00.07 The following describes HP EISA FDDI/9000 products A3659A for servers and B5502A for workstations for HP-UX B.11.00.07. NOTE The HP EISA/FDDI adapter complies with FCC regulatory standards. See the Installing and Administering HP EISA FDDI/9000 and HP HSC FDDI/9000 manual (provided with the product) for the complete FCC Regulatory Compliance statement.

FDDI/9000 EISA Adapter Release Notes Compatibility Information and Installation Requirements Compatibility Information and Installation Requirements Software Requirements • HP-UX 11.0 operating system.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.11.00.07 Patches and Fixes in Version B.11.00.07 The following patches have been incorporated into this version of the FDDI/9000 EISA software: • PHNE_16503 • PHNE_15667 • PHNE_13395 • PHNE_18665 Details regarding these patches and/or fixes follow: Table 1-5 PHNE_16503 Symptom Defect 1. The driver fails to disable previously enabled multicast addresses, with error code set to ‘EINVAL’. 1.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.11.00.07 Table 1-5 Table 1-6 PHNE_16503 (Continued) Symptom Defect 3. lanadmin displays Operation Status as “down(2)” even if the interface is up. 3. The driver was not updating the operation status field in its data structure after the initialization was complete. As a result, incorrect status was displayed by the lanadmin(1M) command. 4. System hangs under heavy network traffic over EISA FDDI. 4.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.11.00.07 Table 1-6 Table 1-7 PHNE_15667 (Continued) Symptom Defect 4. The fddiif utility sometimes reports negative numbers in the statistics. 4. though the statistics are maintained as unsigned integers by the driver, fddiif displayed them as signed values. 5.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.11.00.07 Table 1-7 Table 1-8 PHNE_13395 (Continued) Symptom Defect 3. HPMCs could occur during the execution of the code that autorecovers the interface after transmit time. 3. The transmit hang autorecovery code uses the kernel sleep/wakeup synchronization mechanism t await the completion of events. As autorecovery could be initiated with no process context, the above scheme does not work.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.11.00.07 Table 1-8 PHNE_18665 (Continued) Symptom Defect 3. The system panics with a ‘Data page fault’ when promiscuous mode is repeatedly turned on and off over the EISA FDDI interface. 3. When promiscuous mode is turned on/off repeatedly, there was a time window during which the stream, which had previously turned promiscuous mode off, was closed before the card’s promiscuous mode was turned off by the driver.
FDDI/9000 EISA Adapter Release Notes Patches and Fixes in Version B.11.00.07 EISA FDDI 11.0: New Defect Fixes Besides the above patch fixes, this release also has: 1. Fix for IOVR leak in the EISA FDDI driver. During a card reset, the transmit buffers were not getting unmapped. 2. The fddiif and fddilink commands have been enhanced to support writing their output to a file. A ‘-o’ option has been added to both the commands. 3. After a card reset, multicast addresses enabled previously were not reloaded.
