This section lists the limitations for Tru64 UNIX® for fibre-channel
connections.
- Boot Volumes
- IBM® does
not support FlashCopy® or
Remote Mirror and Copy on Tru64 boot volumes (cluster boot volumes). Do not
attempt to clear persistent reserves on these LUNs.
- UFS file system
- The data will be inconsistent if you perform a FlashCopy on a target LUN which is
online. Take the LUN offline before you perform a FlashCopy.
- AdvFS file system
- It is not possible to access a FlashCopy target volume on the same
host as the source because of domain/fileset advfs concepts. You must unmount
the source volume before you can access the target volume.
From the command
line, type the following commands:
- # umount /source
- # mkdir /etc/fdmns/t_domain (target domain)
- # ln -s /dev/disk/dsk47c dsk47c (target volume)
- # mkdir /target
- # mount -t advfs dsk47c
- # source /target (source is fileset of source volume)
