status so far:
- backup and auto tiering does (and did) not run at the same time
- FLARE has been upgraded last Thuesday to patch level 522
- that brought us only very small improvements since problems seem to be caused by high load on mirrored volumes
- high latencies are observed not in the timeframe where relocation runs
Are there any Mirror View issues know we have to be aware of?
We started moving to a pool concept within one array. That brought us to the situation where we needed to extend the pools with disks which have been freed by migration their LUNs to the pools etc. Without a relocation or restriping process were are stuck in some LUNs located only on the very small number of fresh disks added to the pool shortly before the LUN has been migrated to the pool...
In our opinion the only way would bee to migrate all data off the array and to build pools with their final capacities and then move back all data to the array. Does anyone would like to share his thoughts on that problem?
