Problem description: | |
When running backup operations using IBM Spectrum Protect Snapshot with Storage adapter for CIM devices (SVC,V7K), copy rate setting of FlashCopy pairs outside of IBM Spectrum Protect Snapshot's configuration may get changed if they are not in a consistency group. Customer/Support Diagnostics: Depending on the type of storage system one can see in the audit log commands to change the copy rate coming in with the credentials specified in the profile file. For example in the case of SAN Volume Controller: ,, , ,,,,0,,svctask chfcmap -copyrate= -cim -- With activated traces in the profile file one can see copy rate change commands issued by IBM Spectrum Protect Snapshot fmcima*.trace: SVCHWInterface2::hwChangeCopyRate():4350 Consistency Group: 'FCM', Group Status is 'XXX'.
