after i mounted the new disk, removed the dvd drive, i build a lion usb install device and did a clean install on the ssd, switched the user directory on my old -now second- harddisk. now the boot time for the 10,5 mbp is about 25 sec. installed xcode with the app store + macports for my linux stuff. some small fixes to get vim working correctly (arrow keys, backspace/delete problems):
:set backspace=2
:set nocompatible
the system is much faster, though there is a sata2 bus and the ssd could do sata3 …

a ibm ds4700 with four exp 810 units lost it`s preferred path setting for one controller /some logical drives. consequences : there were some machines with non-redundant paths connected to the san – these machines lost their mounted luns.(datastore for a mail machine, datastore for a fileserver with 14TB…) first i changed on the fibre channel switch fabric the zoneing to the healthy controller and remounted the drives to get the server systems back on production. after some research i seems to be clear that the solution is just only to map the logical drives back to the preferred controller/path … *sigh you can change the controller settings for the logical drives under production scenario. learned: do *all* fc/san connections redundant – don`t save money on your fibrechannel san design … 🙂

upgraded my iphone firmware a few weeks ago from 4.2.1 to 4.3.3 – since the upgrade the phone is running not really stable anymore. sometimes it hangs, sometimes it crashes completly. i can`t figure out what`s causing the problem – but
probably i will wait for ios 5 before downgrading again…
