Greetings!
We ordered a bunch of P7s as part of a hardware upgrade and I was made aware of the Dual Storage IOA configuration. This is something we hadn't fully considered and I was wondering if anyone had done any performance tests using this setup. All our IBM rep told us was "it's slower" and... (1 Reply)
I have a memory card of my Nokia N73 attached to laptop. There are a few partitions.
Why all partitions behave differently? As clear from the attachments, for some partition, delete option is disabled. See 'Disk 1' which is my memory card.

With a sun storage array j4200 with a failed drive.
It's got 11 other drive right now running seagate's
ST314655SSUN146G
I'm about to replace that one drive with seagate's ST3146356SS drive.
Do anyone see this as a problem to use non-Sun drives in Sun storage array or mixing the two... (9 Replies)

I will leave the University I am working, but I need to backup and transfer my research data from UNIX system in our department to my own 750G Hard Drive Storage. But I am not familiar with UNIX. How to do this? Thank you. (5 Replies)
AMTAPE(8) System Manager's Manual AMTAPE(8)NAME
amtape - user interface to Amanda tape changer controls
SYNOPSIS
amtape config command [ command options ]
DESCRIPTION
Amtape performs tape changer control operations. It uses the underlying tape changer script defined by the tpchanger option for a particu-
lar Amanda configuration as specified by the config argument.
Tape changers maintain a notion of the current and next slot for each configuration. These may or may not correspond to an actual physical
state of the device, but do tend to minimize searching through the tape storage slots. If the desired tape is in the current slot, it is
likely the next tape needed is in the next slot rather than at some random position in the storage slots.
See the amanda(8) man page for more details about Amanda.
COMMANDS
reset Reset the tape changer to a known state. The current slot is set to the first slot. Other device-specific side effects may occur.
Some gravity stackers need to be reset to the top position by hand. This command notifies Amanda the stacker is back in that posi-
tion.
eject If a tape is loaded in the drive, it is ejected and returned to the slot from which it was loaded.
clean If a cleaning tape is defined for the changer, it is used to clean the drive.
show Show the contents of all slots. This can be slow.
label label
Search for and load the Amanda tape with label label.
taper Perform the taper scan algorithm. Load the next tape in the configuration's tape sequence, or a fresh tape with a suitable label.
device Display the name of the current tape device on stdout.
current
Display the current slot.
update Update the changer label database, if it has one, to match the tapes now available.
slot slot
Eject any tape in the drive and put it away, then load the tape from slot slot and reset current.
slot current
Eject any tape in the drive and put it away, then load the tape from the current slot.
slot prev
Eject any tape in the drive and put it away, then load the tape from the previous slot and reset current.
slot next
Eject any tape in the drive and put it away, then load the tape from the next slot and reset current.
slot first
Eject any tape in the drive and put it away, then load the tape from the first slot and reset current.
slot last
Eject any tape in the drive and put it away, then load the tape from the last slot and reset current.
slot advance
Eject any tape in the drive and put it away. Advance current to the next tape, but do not load it.
This is useful with non-gravity stackers to unload the last tape used and set up Amanda for the next run. If you just use eject,
the current tape will be mounted again in the next run, where it will be rejected as being still in use, ejected and the next tape
requested. Using slot next followed by eject does an unnecessary mount.
Note: most changers optimize the slot commands to not eject the loaded tape if it is the one being requested.
