All,
I need to replace several 4.3GB drives in my esa10000 cabinet. I intend to replace them with 18gb drives. What I am wondering is if anyone knows how much time I should allow for building the storage sets.
Part 1 - hsz
At present, I have a RAID 5 storage set behind a dual-redundant HSZ70 (I have firmware v7.3 on order to support the 18gb disks). It is a ten disk set (long story). The disks in question are all 4.3 gb, and what I intend to do is replace them with 18GB disks. I also want to divide the 10 disk set into two 5 disk sets. Does anyone have a handy "rule of thumb" (or proven formula) for predicting how long it will take the hsz70 to construct these 5-disk raid5 sets?
part 2 - LSM
The storage units on my hsz's are constructed identically on another bus (and pair of dual-redundant hsz's). This is in turn mirrored via LSM. The LSM volumes in turn have AdvFS filesets on them that are part of a shared disk service between two 4100 nodes. The 4100's are 1gb RAM, two processor (533MHZ). The hsz's connect to kzpsa's at the end of each bus in each host; hosts run Tru64 v4.0d with pk#2 and TCR 1.5 with pk#2.
I expect I will have to destroy the existing LSM volumes and redefine the subdisks, plexes, and volume with new sizes. So, are there any rules of thumb again for how long it will take LSM to a) start the volume initially on the 5x18 gb storage set from part 1?; and b) how long to sync the two halves of the mirror?
Any insights, formula's, rules of thumb, etc., most welcome!
Thanks in advance
