AIX Device Driver (Atape) - TS3400 (3577) Library - TS3500 (3584) Library - Ultrium TD4 LTO drives - TS3100 (3573-L2U) Library - TS3200 (3573-L4U) Library - TS3500 (3584) Library - Ultrium TD3 LTO drives - TS3100 (3573-L2U) Library - TS3200 (3573-L4U) Library - TS3500 (3584) Library Note: Using a single Fibre Channel host bus adapter (HBA) for concurrent tape and disk operations is generally not recommended. Tape and disk devices require incompatible HBA settings for reliable operation and optimal performance characteristics. Under stress conditions (high I/O rates for either tape, disk, or both) where disk and tape subsystems share a common HBA, stability problems have been observed. These issues are resolved by separating disk and tape I/O streams onto separate HBAs and using SAN zoning to minimize contention. IBM is focused on assuring server/storage configuration interoperability. We strongly recommend that your overall implementation plan includes provisions for separating disk and tape workloads. Software Requirements The AIX Enhanced Device Driver (Atape device driver) supports AIX 5L™ Version 5.2 and later releases on IBM POWER-based AIX servers. To obtain the most current service and documentation for this software, refer to Appendix A, "Accessing Documentation and Software Online," on page 341. Installation and Configuration Instructions The recommended procedure for installing a new version of the device driver is to uninstall the previous version. Instructions for uninstalling the device driver are outlined below in "Uninstalling" on page 28. Attention: At the end of the installation procedure, the installp facility automatically runs the AIX bosboot command to update the boot record with the newly installed Atape files. When the bosboot command completes, the following messages are displayed: 0503-292 This update does not fully take effect until after a system reboot. installp: bosboot process completed. This message is referring to the updates to the boot record only. If the installation summary shows that the Atape driver was installed successfully, it is not necessary to reboot the machine at this time. If the installation summary shows that the install failed, you should reboot the machine and attempt to install the Atape driver a second time. 26 IBM Tape Device Drivers Installation and User's Guide
