Write intention log for mirror view replication place-URGENT?
Hello everybody,
is there any way to place Write Intention Log (WIL) for mirror view replication configuration on Storage Pool in VNX5300?
Or is it mandatory to place it on RAID Group? I have used all disks in storage pools and only way to create radi groups is to destroy everything and build from scratch but offcourse I have large numbers of VM's. Any help would be very apreciated...
TIA,
Dragan

Dragancili,
Firstly, welcome to the forums, and thank you for being an EMC customer.
You would find, or maybe already tried, that Unisphere (and naviseccli) prevents you from placing the WIL on pool LUNs (thin or thick). There isn't any way to circumvent this and is strictly enforced.
If all of your disks have been bound in pools, you could also consider placing them on the remaining space on the system drives (first 4 drives). This is also suggested in the "MirrorView Knowledge Book" available on Powerlink via the following breadcrumb trail:
