Use this attachment package with the documentation for the IBM ESS TotalStorage Host Systems Attachment Guide. The following lists history of the HA packages: - V32.6.100.29 - V32.6.100.27 - V32.6.100.25 - V32.6.100.24 - V32.6.100.23 - V32.6.100.22 - V32.6.100.21 - V32.6.100.19 - V32.6.100.18 - V32.6.100.17 - V32.6.100.16 - V32.6.100.15 - V32.6.100.13 - V32.6.100.12 - V32.6.100.9 - V32.6.100.8 - V32.6.100.7 - V32.6.100.6 - V32.6.100.4 The following provides descriptions of each HA update for AIX. V32.6.100.29 ============ This version includes two new attributes, clr_q with default value "no" and q_err with default value "yes". V32.6.100.27 ============ This version includes a new sdd_model_map attribute. With this new attribute, SDD configuration methods will generate a unique_id attribute for each SDD vpath device. This version also fixes a problem with the max_transfer attribute not displaying correctly in the output of the "lsattr" command. The mode_data attribute now includes the mode page A data. The lun_id and scsi_id attribute have been changed to displayable but not user changeable. V32.6.100.25 ============ This version checks that the Host Attachment for MPIO is not installed before allowing installation of this package. V32.6.100.24 ============ This version adds new environment variable checking during upgrade. The new environment variable, SDDHDISK_ON_ROOTVG, is used when customers intend to upgrade the HA package while one or more 2105 hdisks belong to the rootvg volume group. If it is set to YES, upgrade continues(Reboot is advised so that hdisks are reconfigured with new ODM attributes). If set to NO, all 2105 hdisks must be removed before upgrade can continue. If upgrading from v31.6.100.19 or below, you may encounter an ODM corruption after upgrade. Please contact your IBM technical support to correct ODM in this case. Also, refer to the following SDD AIX FLASH website for details: http://www-1.ibm.com/support/docview.wss?rs=540&context=ST52G7&dc=D600&q1=ODM&uid=ssg1S1002295&loc=en_US&cs=utf- 8&lang=en V32.6.100.23 ============ This version adds one new attribute to the odm, max_transfer. This attribute allows user to change the maximum data transfer size of a device. The default value is set to 40,000. V32.6.100.22 ============ This version does not allow installation of the ibm2105.rte Host Attachment if ibm2105.rte version 32.6.100.19 or earlier is installed on the system, and hdisks are configured. Users must remove all 2105 hdisks and SDD vpath devices from the host system prior to upgrading. This will help users avoid potential ODM corruption. V32.6.100.21 ============ This version contains support for ESS scsi, fcp, and iscsi devices. A new attribute was also added to this version to support parallel configuration. Starting from this release(32.6.100.21), ESS FC devices will be configured as "IBM FC 2105", as seen from the "lsdev -Cc disk" output. This is changed from "IBM FC 2105XXX", where 'XXX' is the ESS device model, such as F20 or 800. Because of this change, you will need to remove all ESS FC hdisks and SDD vpath devices from your host system prior to installing or upgrading to this version of ibm2105.rte. V32.6.100.19 ============ This version adds support for the new ESS model 750. V32.6.100.18 ============ This version adds two new attributes to the odm, scbsy_dly(scsi and fcp) and qfull_dly(fcp only). These two attributes will prevent several host failures caused when ESS is in a long busy state and returns queue full. V32.6.100.17 ============ This version does not ship any new ODM stanzas. This version only includes a check to make sure the host attachment that supports MPIO is not installed on the host system already. If the host attachment for MPIO is installed on the host already, the installation of this package will fail. V32.6.100.16 ============ This version provides support for FC dynamic device tracking. It also provides a new device attribute "lun_reset_spt" with default value set to 'yes' to support scsi-3 lun_reset command for ESS devices. V32.6.100.15 ============ This version does not ship any new ODM stanzas. There are only changes to the packaging to make sure there are no other versions of ibm2105.rte on the system already. V32.6.100.13 ============ This version fixes a duplicate entry bug in the ODM. V32.6.100.12 ============ This version provides support for the new IBM 2105800 model. This version also includes ODM entries of the PR for all Shark model. V32.6.100.9 =========== This version provides support for Network Installation Management (NIM). You can install the IBM2105.RTE from a NIM master machine to multiple NIM AIX client machines. There are no new ODM stanzas. There are no changes to the existing ODM stanzas in the fileset. You need the following filesets for NIM support: - devices.fcp.disk.ibm2105.rte - devices.scsi.disk.ibm2105.rte If you do not plan to use the NIM feature and are currently at version v32.6.100.7 or above, you are not required to install IBM2105.RTE version v32.6.100.9. V32.6.100.8 =========== This version provides a non-disruptive upgrade feature. When you install a new version of IBM2105.RTE, you are not required to run the varyoff command or deinstall the old version. There are no new ODM stanzas. There are no changes to the existing ODM stanzas in the fileset. You are not required to install this version if you are currently at version v32.6.100.7. IBM recommends that you install version 32.6.100.8 if you have version v32.6.100.6 or lower. V32.6.100.7 =========== This version fixes the bosboot absence problem. The bosboot command was not executed after a successful installation of IBM2105.RTE version v32.6.100.6. V32.6.100.6 =========== For this version, the queue_depth setting was reduced to 20 based on the findings from the performace group. V32.6.100.4 =========== For this version, IBM added ODM stanzas to support fibre-channel subsystem disks and support for the IBM 2105 Model F10/F20. ---------------------------------------------------------------------------------------------- 3.0 Procedure for upgrading AIX OS, Host attachment, and/or SDD Please refer to the latest SDD readme file for the detailed procedure. ----------------------------------------------------------------------------------------------- 4.0 User license agreement for IBM NOTICE: PLEASE READ THIS AGREEMENT CAREFULLY BEFORE USING THE PROGRAM AND DOCUMENTATION.
