Patch Name: PHNE_17022 Patch Description: s700_800 10.20 EISA Mux driver/utilities cumulative patch Creation Date: 99/01/22 Post Date: 99/01/27 Hardware Platforms - OS Releases: s700: 10.20 s800: 10.20 Products: EISA-MUX B.10.20.00 EISA-MUX B.10.20.01 EISA-MUX B.10.20.02 EISA-MUX B.10.20.03 EISA-MUX B.10.20.04 EISA-MUX B.10.20.05 EISA-MUX B.10.20.06 Filesets: EISA-MUX.EISA-MUX-KRN EISA-MUX.EISA-MUX-RUN Automatic Reboot?: Yes Status: Special Superseded Critical: No (superseded patches were critical) PHNE_9026: HANG Path Name: /hp-ux_patches/s700_800/10.X/PHNE_17022 Symptoms: PHNE_17022: 1) Port 4 on 8-Port EISA mux to D-series does not work PHNE_16384: 1) Output garbage that hangs modem on EISA mux 2) System panic in EQNX_sst_proc on stack trace on EISA mux 3) Read(2) not reading data although select(2) returns true 4) Data flow will not restart again with tcflow on EISA mux 5) FIONREAD call does not work correctly on EISA mux 6) Use HW path instead of slot number for EISA mux PHNE_11667: UPS failed to work on EISA mux in by-pass mode. Select interface failed to work on EISA mux in by-pass mode. PHNE_9026: VTIME > 0, VMIN = 0 caused raw mode read to return in less time than specified in VTIME. VsiFax software failed to work due to above VTIME/VMIN problem. Select system call hangs on EISA mux port. Screen froze when running telnet on EISA mux port due to the above failure on the select system call. Defect Description: PHNE_17022: Logic error in driver that handles 8-Port EISA mux causes Port 4 to fail. Resolution: The fix was to change the logic associated with the calculation of the channels associated with the hardware to make Port 4 work PHNE_16384: 1) Logic error in enabling opost processing in HW. 2) Typo error caused a missing "&" for address of a variable 3) Logic error in by-pass mode processing. 4) Logic error in handling flow control. 5) FIONREAD was not processed in by-pass mode. 6) This is an enhancement for support multi-node V class PHNE_11667: This problem was casued by a logic error in the by-pass mode select interface. PHNE_9026: The first problem was caused by a logic error in the by-pass mode of the EISA mux driver handling the VTIME > 0 and VMIN = 0 case incorrectly. The second problem was caused by the fact that the driver was mistakenly sleeping on the process instead of the kernel thread.

Back up your system before installing a patch. 2. Login as root. 3. Copy the patch to the /tmp directory. 4. Move to the /tmp directory and unshar the patch: cd /tmp sh PHNE_17022 5a. For a standalone system, run swinstall to install the patch: swinstall -x autoreboot=true -x match_target=true \ -s /tmp/PHNE_17022.depot 5b. For a homogeneous NFS Diskless cluster run swcluster on the server to install the patch on the server and the clients: swcluster -i -b This will invoke swcluster in the interactive mode and force all clients to be shut down. WARNING: All cluster clients must be shut down prior to the patch installation. Installing the patch while the clients are booted is unsupported and can lead to serious problems. The swcluster command will invoke an swinstall session in which you must specify: alternate root path - default is /export/shared_root/OS_700 source depot path - /tmp/PHNE_17022.depot To complete the installation, select the patch by choosing "Actions -> Match What Target Has" and then "Actions -> Install" from the Menubar. 5c. For a heterogeneous NFS Diskless cluster: - run swinstall on the server as in step 5a to install the patch on the cluster server. - run swcluster on the server as in step 5b to install the patch on the cluster clients. By default swinstall will archive the original software in /var/adm/sw/patch/PHNE_17022. If you do not wish to retain a copy of the original software, you can create an empty file named /var/adm/sw/patch/PATCH_NOSAVE. Warning: If this file exists when a patch is installed, the patch cannot be deinstalled. Please be careful when using this feature. It is recommended that you move the PHNE_17022.text file to /var/adm/sw/patch for future reference. To put this patch on a magnetic tape and install from the tape drive, use the command: dd if=/tmp/PHNE_17022.depot of=/dev/rmt/0m bs=2k Special Installation Instructions: Install this patch only on a system that is equipped with an EISA bus and with an EISA mux card installed.
