Poor provisioning tools annoy me. I've been annoyed today. I've been changing some VMware metas from 100GB to 200GB on a DMX. Unfortunately they were already presented (but not used) and replicated with SRDF. So I had to:
- "Not Ready" the R1 and R2 drives
- Unmask the LUNs from the FA
- Split the SRDF relationship
- Break the SRDF relationship
- Unmap the LUNs from their FAs
- Dissolve the metas
- Create the metas
- Re-establish and resync SRDF
- Map the LUNs to the FA
- Mask the LUNs to the hosts
10 steps which take some considerable time to write validate and execute. I don't do this stuff often enough to justify writing scripts to help me out; but I think this should be a vendor thing - a software tool with various configure options that creates the symconfigure and associated commands for you and indicates the steps you will have to perform. ECC is *supposed* to do it but it doesn't. Roll on some good software.

Chris,
I spent a long time today and the last few days spending TONS of my time waiting for HDS HiCommand Device Manager screens to refresh. I kid you not, if I didnt have to wait for screens to refresh and terrible lags waiting for the next screen to load I could have accomplished 3 days work in half a day!! I repeat, I kid you not. It has been a painful few days waiting for SLOW software.
Good hardware..... errr not so good software (to put it mildly).
