Crash Recovery for Solaris-Based Servers

Restore the system from a 4 mm DAT tape or a replacement system disk. Use the Solaris ufs-
restore procedure. The tape drive can reside on any network-connected Solaris server and can be
accessed directly or remotely using the rmt facility in Solaris. You can use a bootable Solaris
installation CD to restore from tape.
Use the Unix Windows file server software (Samba) to backup and restore non-system data for the
Windows based servers. This approach makes the server appear as a standard Windows file sever.
File sharing, storage, retrieval and so on is performed without additional client software installed on
the Windows based stations.

About this task
MPS software loads on T4 includes a few HDD copy scripts in the /etc directory as follows:
• /etc/WWNcopyHDD
- Utilizes ufsdump and ufsrestore to automate a disk-to-disk copy of a single bootable HDD.
- Based on existing Avaya D2DBkup script.
- The use of dd is not recommended.
• /etc/WWNupdateVFSTAB
- Updates the /etc/vfstab file on the new HDD so it includes the appropriate unique WWN
data.
• /etc/WWN_replace_mirror_hdd
- Assists in the replacement of a HDD drive in a mirrored system. (This is covered separately
in mirroring documentation)
The following is an example of a Disk-to-Disk Copy (HDD0 to HDD1):
Partitions: d0s0, d0s4, d0s5, d0s6 and d0s7 (standard for MPS)
HDD0 and HDD1 are identical hard disk drives (P/N) and will be copied with identical partitioning
maps. When different partitioning is required simply answer "n" for no when prompted to utilize
identical partitioning.
The WWNcopyHDD bypasses the partitioning altogether and start at creating new filesystems on
existing partitions. So if partitions are not in order, the copy will fail.
Example: boot –s disk0 (HDD0 is the known working HDD to be copied)
