https://community.hpe.com/t5/storeever-tape-storage/5300-tape-array-and-device-open-problems/m-p/3012785#M7850 just installed a "refurbed" 5300 tape array on a rp7400. when we plug in a DLT 8000 from a good working system we get: "on tape open: No such device or address". ioscan -fnC tape sees this device, and device files are there (from insf -e). we can even see a daisy-chained Ultrium 230 (external device) on the same SCSI chain. moved the DLT back to the working 5300 and it works fine again. any suggestions? my guess is a bad 5300 Wed, 02 Jul 2003 01:46:42 GMT David Uraneck 2003-07-02T01:46:42Z https://community.hpe.com/t5/storeever-tape-storage/5300-tape-array-and-device-open-problems/m-p/3012785#M7850 just installed a "refurbed" 5300 tape array on a rp7400. when we plug in a DLT 8000 from a good working system we get: "on tape open: No such device or address". ioscan -fnC tape sees this device, and device files are there (from insf -e). we can even see a daisy-chained Ultrium 230 (external device) on the same SCSI chain. moved the DLT back to the working 5300 and it works fine again. any suggestions? my guess is a bad 5300 Wed, 02 Jul 2003 01:46:42 GMT https://community.hpe.com/t5/storeever-tape-storage/5300-tape-array-and-device-open-problems/m-p/3012785#M7850 David Uraneck 2003-07-02T01:46:42Z https://community.hpe.com/t5/storeever-tape-storage/5300-tape-array-and-device-open-problems/m-p/3012786#M7851 <BR />tape array internal cabling can be finnicky. <BR /><BR />There is not much that can be done, apart from replacing the backplan under warranty or the entire array. I assume you have tried different slots.<BR /><BR />Be aware that there is a fair old run of cabling inside the arrays and you shouldn't daisy chain more than a couple of devices on the same bus within the array Tue, 08 Jul 2003 09:41:16 GMT https://community.hpe.com/t5/storeever-tape-storage/5300-tape-array-and-device-open-problems/m-p/3012786#M7851 madoc 2003-07-08T09:41:16Z
