Fix dynamic reconfiguration defects in SUN SDD release 1.4.0.7. a. Lift the restriction of stopping IO while running "cfgvpath -r". b. Fix a problem that when "same path" is added back through "cfgvpath -r" after removed by "cfgvpath -r", the path will show up as an additional path on the vpath device. Fix made to use the original path before removed. c. Fix a bug so that paths are not removed from vpath devices when devices are busy. d. Fix a bug so that it will not try to remove the same vpath device twice. 3.1.2 ESS defects 3.1.3 SVC defects =============================================================================== 3.2 New Features 1. Support Solaris 9 for ESS 2. Support New device SVC Cisco MDS 9000 3. Support Veritas Volumer Manager 3.5 MP2 or later =============================================================================== 3.3 Feature Details Support for Veritas Volume Manager SDD supports ESS devices for Veritas Volume Manager 3.5 MP2 or later Case 1: Installing Veritas Volume Manager for the first time. 1. Install SDD using the procedure in the Installing SDD section, if you have not already done so. 2. Install the Veritas Volume Manager package. 3. Follow the procedure in Veritas Volume Manager manual to create rootdg disk group and other required groups. In Veritas Volume Manager, the ESS vpath devices will have names such as VPATH_SHARK0_0, VPATH_SHARK0_1, etc. Case 2: Installing SDD with Veritas already installed. 1. Install SDD using the procedure in the Installing SDD section. 2. Reboot the host system. In Veritas Volume Manager, the ESS vpath devices will have names such as VPATH_SHARK0_0, VPATH_SHARK0_1, etc. Note: All ESS devices managed by DMP before SDD installed will be managed by SDD after SDD is installed. =============================================================================== 3.4 Known Issues The following table lists the known problems and recommended workarounds for this release of the Subsystem Device Driver: ================================================================= Item Description ================================================================= 1. Patch 108968-02 causes the volume manager to hang in the middle of mounting the Subsystem Device Driver CD on a Sun server running Solaris 8. 2. Message, "Warning: Failed process interrupt for vpathdd0 due to down-rev nexus driver Pseudo0" (This message shows up during the installation and reboot time on Solaris 8 only.) ================================================================== Details ================================================================== 1. The patch 108968-02 causes the volume manager to hang in the middle of mounting the Subsystem Device Driver CD. We recommend that you upgrade Solaris 8.0 to the latest accumulative patches, 108528-08 and beyond. If you do not have the latest patches installed or if the Subsystem Device Driver CD installation process fails when installing on a Sun server running Solaris 8 patch 108968-02, use the following procedure as a workaround. "Installing the Subsystem Device Driver CD on a Sun server running Solaris 8 patch 108968-02" Perform the following steps: 1. Stop volume manager by typing this command: /etc/init.d/volmgt stop 2. Insert the CD in the CDROM 3. Manually mount by typing this command: mount -F hsfs -o ro /dev/dsk/cxtydzs0 /mnt (where cxtydzs0 is the special file for the CDROM in the intend server) 4. Install the package by typing either one of the following commands: For 32-bit applications, type: pkgadd -d /mnt/sun32bit IBMdpo For 64-bit applications, type: pkgadd -d /mnt/sun64bit IBMdpo 5. Unmount the CD by typing this command: umount -a /mnt 6. Remove the CD by typing this command: eject /dev/dsk/cxtydz 7. Restart the volume manager by typing this command: /etc/init.d/volmgt start 2. The message, "Warning: Failed process interrupt for vpathdd0 due to down-rev nexus driver Pseudo0" occurs. This message shows up during the installation and reboot time on Solaris 8 only. This message will not impact the normal Subsystem Device Driver installation and operation because the VPATHDD device driver does not require interrupt handling by the underlying PSEUDO nexus device driver. The VPATHDD device driver interrupts are the same as the underlying SCSI HBA interrupts, which are generated through the hardware bus, such as the PCI and SBUS, and are handled by the corresponding PCI or SBUS nexus device driver. Hence, it does not require any handling through PSEUDO nexus device driver. ------------------------------------------------------------------------------- 4.0 User license agreement for IBM device drivers NOTICE: PLEASE READ THIS AGREEMENT CAREFULLY BEFORE USING THE PROGRAM AND DOCUMENTATION.
