Problem description: | |
In using a shared disk configuration on AIX, with DB2 and TSA, if you have one volume group consisting of multiple file systems, after failover, some resource groups could be in a "Pending Offline" state. For Example, you have a VG called "db2vg1" with mulitple DB2 filesystems, for logs, tablespaces etc, like the following: /db2/db2inst1 <-- DB2 instance home /db2/db2inst1/log_dir <-- DB2 log directories /db2/db2inst1/temp1 <-- DB2 temporary space /db2/db2inst1/data1 <-- DB2 data space /db2/db2inst1/data2 <-- DB2 data space /db2/db2inst1/db2dump <-- DB2 diagnostic data After a failover operation, the lssam output (shown below), may indicate several DB2 mount resources are in "Pending Offline", eventually reaching a Failed Offline" or "Stuck Online" state. ------lssam output snippet------ **Pending offline** IBM.ResourceGroup:db2_db2inst1_0-rg Request=Lock Binding=Sacrificial Control=SuspendedPropagated Nominal=Online |- Offline IBM.Application:db2_db2inst1_0-rs Binding=Sacrificial Control=SuspendedPropagated |- Offline IBM.Application:db2_db2inst1_0-rs:hostname01 '- Offline IBM.Application:db2_db2inst1_0-rs:hostname02 >><< Binding=Sacrificial Control=SuspendedPropagated |- Offline IBM.Application:db2inst1-db2_db2inst1-rs:hostname01 '- Online IBM.Application:db2inst1-db2_db2inst1-rs:hostname02 |- **Pending offline** IBM.Application:db2inst1-db2inst1_log_dir-rs Binding=Sacrificial Control=SuspendedPropagated |- Offline IBM.Application:db2inst1-db2inst1_log_dir-rs:hostname01 '- **Pending offline** IBM.Application:db2inst1-db2inst1_log_dir-rs:hostname02 ------------------------------------- | |
