How to configure EMC storage on HPUX

1. Install EMC host base agentmount-F CDFs-O cdcase on the client
/Dev/DSK/c0t0d0/CDROM (only such a mount can read the correct EMC disc) swinstall-S/CDROM 2. Create a raid group (group 3) on the EMC Manager server) 3. Create Lun (Lun 8) on the raid group 4. Create a new storage group (js-wap01) 5. On the storage group (js-wap01) add js-wap01 to hosts (right-click js-wap01 --> Properties) 6, add Lun 8 to luns7 in storage group (js-wap01), you can see the js-wap01 in hosts (top tab, open Luns, and you will see that the hardware number is c8t0d0 8, failover on EMC, And the menu is tools --> failover Setup Wizard parameter is configuration Summary

/Dev/DSK/c11t0d0/dev/rdsk/c11t0d010. Create a physical volume:
# Pvcreate/dev/rdsk
/C8t0d0

11. Create a volume group
11.1 create a directory under/dev with the volume group name.
If the volume group name is vg_miscfile, the directory is/dev/vg_miscfile.
# Mkdir/dev/vg_miscfile.
11.2 create a set of device files for the volume group in this directory.
# Mknod/dev/vg_miscfile/group C 64 0x010000
12. Create a volume group (with the physical volume as the parameter ):
# Vgcreate/dev/vg_miscfile/dev/DSK/c8t0d0.
After creation, run the command: vgdisplay to check whether the settings are correct. 13. Create a logical volume.
When creating a logical volume, the corresponding character devices and Block devices are generated under the volume group directory.
Now, create the following logical volume in the volume group vg_miscfile:
A 512 MB logical volume named lv_miscfile.
# Lvcreate-l 512-N lv_miscfile/dev/vg_miscfile parameter:-L indicates the logical volume size in MB.
-N indicates the logical volume name. The default value is lvol1, lvol2 ...... [HPUX] If Multiple Volume groups are involved, it is best to add the name of the volume group, for example, # lvcreate-N lvname vgname

14. Compile the file system.
Run the following command to create a JFS File System on/dev/vg00/lvoldb01:
# Newfs-F vxfs/dev/vg_miscfile/R

Lv_miscfile Note: There must be letters R
# Newfs-O largefiles-F vxfs/dev/vg_cdrlog/rlv_cdrlog create a large file system # fsadm-F vxfs-O largefile/oralce modify the file system to a large file system

15. Mount the file system.
15.1 create a mount point: # mkdir/miscfile15.2. Use mount to mount:
# Mount-F vxfs/dev/vg_miscfile/lv_miscfile/miscfile.
Currently, BDF is available to display all pending volumes.

I/O error indicates that the Failover function has not been configured on EMC. HP UX can be seen through ioscan, but cannot be controlled.
# Pvcreate/dev/rdsk/c10t0d0
Pvcreate: the physical volume already belongs to a volume group
It indicates that c10t0d0 is the replaceable connection of PV in VG, And it is/dev/rdsk/c8t0d0. It also indicates that the replaceable connection does not need to be created by pvcreate.
Note 1: When the EMC host base agent is not installed on hp unix, UX can see four disks (ioscan-fncdisk), which are actually a lun and different connection paths, but it cannot be read or written. NOTE 2: After the agent is installed, the UX can be seen, but cannot be read or written. NOTE 3: After configuring Lun, raid group, and storage group on EMC, UX can read and write c8t0d0 and c10t0d0 (the Lun is controlled by the SP ), c9t0d0 and c11t0d0 cannot read and write annotations 4: After failover is configured on EMC, UX can read and write all four paths # strings/etc/lvmtab
