before the admin shutdown vio server lpar, admin must remember the following points: partition accesses its paging space device using vio server lpar that the admin is planning to shutdown. p.s: please refer the redhat ibm pdfs for detailed understanding! 1. all the file systems exist on top of logical volume. no file system can exist without logical volume. although lv does exists without a file system. first a lv is created and on top of it a fs is created. system first creates a lv. then, a layer of jfs is created on top of 2. whenever a file system is expanded, logical volume (lv) is extended first. then the layer of jfs on top of it is expanded and finally the 3. aix has a limit of only 3 copies of lv. these copies may be in sequential or parallel arrangements. 4. in case system crash takes place, mirror write consistency check (mwcc) method is performed in order to track the last 62 writes to the 5. in normal vg configuration, a vg can never have more than 32 pvs as vgda design has a limit and is always fixed in size. vg will not take              v.      lv size (maximum) = 32 x 1016 x 128 = 8.3 tb (approx.) most of the information is already available in various red hat ibm pdfs and online books. this post will discuss about the system boot with respect to hardware. as we have already seen, bosboot command is used to create boot image from disk files and copies boot image to blv. if a machine keeps rebooting and repeating post, it means either there is invalid bootlist or corrupted blv or hardware failure of boot login to hmc using ssh, login as hscroot user and run the following command: cbu basically means processors or memory temporarily added to backup server. cod means ability to activate the processors or memory resources temporarily. hacmp version 5.4 supports non ibm harwares as well and operating systems like red hat linux and suse. p.s: information published in this post is inspired from various red hat pdf’s and online sources.
