What happens if I metainit a running filesystem? for example : df -k output for root filesystem: /dev/md/dsk/d1 493063 271646 172111 62% / then I do a metainit on d1 from entries in md.tab what will happen

Oh yes!!! controllers will do change!!! Thanks

Hi daFranze, Assuming the server needs to be installed from scratch, but the data is in an external drives. Can I do the following to mount the disk from external drives 1. copy the output of metastat -p to md.tab 2. remove 1 submirrors for all mirrored configuration ex: OLD: d1 -m d0 d4 1...

Hi daFranze, I encoutered an error during metattach maxtransfer is too small # metattach d6 c25t16d38s3 metattach: uxedm1a: c25t16d38s3: maxtransfer is too small how can I check the maxtransfer of each devices? how can I change the maxtransfer for each device? Thanks

Thanks again daFranze!

Hi daFranze, Ok we will be aware of that. I have another question, can we add a new disk smaller than the existing disk in the RAID5 configuration? Thanks

hmmmm... from the SDS manual it says it can but there is not parity on the added disk. it also just concatenates it. is this safe?

Hi Gurus, I'm planning to expand a filesystem that has a RAID 5 protection using SDS. What things should I consider before doing the expansion? What are the limitation of expanding a RAID 5? Can I just expand and expand a RAID5? Thanks gurus!

Hi, in the scenario above... If I edit /etc/lvm/md.tab then do the metainit -a can I do a mount on all of my filesystem? will metainit erase/format my data in the disk? Thanks

Hi, I'm not really familiar with SDS. I've read the user guide of SDS and I could not find commands that i'm looking for. here is a "wild" scenario... for example the server is running fine. the file system /u01 is residing on an External Storage through SAN using SDS. at one point the root...

daFranze, this is something like host mirroring/migration right? I was thinking to mounting the file system to the 2nd storage. scenario : Storage 1 and Storage 2 has the capability of mirroring (remote mirror) hardware level. 1. Server 1 is connected to Storage 1 2. start mirroring from...

Hi daFranze, Actually we are not moving the data from one host to another. We just move the data from one storage to another. what is the equivalent IBM command for varyoffvg, exportvg, varyonvg and importvg in SDS? Thanks

Hi gurus! We plan to migrate a server from one storage to another. The filesystem uses Solstice Disk suite to do host mirroring and raid. I'm not familiar with disk suite. Can anyone give me a document on how to do this? We will use remote mirroring to copy the data from storage to another...

Thanks everybody. I understand now. until next post! :)

how can I find the disk used by these filesystems? or is this a filesystem mounted from another fileystem? Thanks

Hi gurus, sorry for the late reply let me create another example output df -k /prodoper/onis 1523502 1127652 380615 75% /usr/onis output mount /usr/onis on /prodoper/onis read/write on Mon Aug 9 16:19:13 2004 output of vfstab (no relevant info) #device device mount FS fsck...

Hi gurus! I ran df -k on one server there is one line that looks like this /export/home/home_it/roy 2052870 1724428 307914 85% /home/roy instead of /dev/dsk/c4t0d3s1 8695492 7659910 948628 89% /db/dbars/admin what kind of filesystem is this? how will I know which disk is...

daFranze, If I use ifconfig to change the MAC address and the system reboot will the changes be in effect after reboot? or should I add something to rc.d. which file? Thanks

daFranze, how can I make sure that the MAC I will enter is unique? dbase77, I'll try that. Thanks
