SymptomsIf your hardware includes SCSI tape connected to the Sun 7000 unified storage and if you are running the software version 2010.Q1.0.*, you will experience a slow tape read or write performance, and thus the backup and restore may be slower as well.Use the following steps to check. BUI Status/NDMP can tell you the inquiry strings of the library/tape drive, so you know the make/model. Also, you can check BUI Maintenence/Hardware to find out if you have a FC card or a SCSI card in the chassis. BUI Analytics provides NDMP Bytes/Sec transferred to/from Tape, can show you the tape performance. If the tape performance is around 2mbps then you are hitting this issue. CauseThis is due to a software bug.<SUNBUG: 6932154> SolutionThe above bug has been fixed in 2010.Q1.1.0 software release, a software upgrade to the latest released is required to resolve this issue.References<BUG:6932154> - WCREG14:ADD MEMBER NOTIFICATION- UNABLE TO ADD COMMENTSAttachments This solution has no attachment |
