18 HP StorageWorks Disk Array XP Operating System Configuration Guide: HP-UX Dev ice emulation types The XP famil y of disk arrays supports the se device emulat ion types: ⢠OPEN-K/3/8 /9/E devices: OPEN-x logic al units represent di sk devices. Exce pt for OPEN-V , the se devices are ba sed on fixed sizes. OPEN- V is a user -defined size. Support ed emulati ons include OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN- L, and OPEN-V device s. ⢠LUSE devices (OPEN- x *n ): Logical Uni t Size Expansion (LUSE) devices combine 2 to 36 OPEN- x devices to c r eate expanded LDEVs lar ger than s tandard OPEN-K/3/ 8/9/E disk devic es. For example, a n OPEN-x LUSE volume create d from ten OPEN-x volumes i s designated as OPEN-x*10. ⢠CVS devices (OPEN-x CVS): V olume Size Conf iguration ( VSC) defines custom volu m es ( CVS) that are s maller than n ormal fixed- sized logica l disk dev ices (volumes ). (OPEN-V is a CVS-based c ustom dis k size that you dete rmine. OPEN- L does not support CV S.) ⢠LUSE (expanded) CVS devi ces (OPEN-x*n CVS): LUSE CVS combin es CVS devices to create a n expanded devi ce. This is don e by firs t creating C VS cus tom-sized devi ces an d then usi ng LUSE to comb ine from 2 t o 36 CVS devices. F or example, if thr ee OPEN-9 CVS volumes are combi ned to cre ate an expanded device, this de vice is designat ed as OPEN-9*3-CVS.

The physica l volumes that make up one volu m e group c an be located either in the same disk arra y or in other disk arrays . T o allo w m ore volume groups to be created, use SAM to modi fy the HP-UX sys t em kernel confi guration. See appendix C (page 73) fo r details. T o cre ate volume gr oups: 1. Use th e vgdis play command to dis play the exist ing volume group s. 2. Choose a unique name for the new volume gr oup (f or exa mple: vg06). 3. Create t he director y for the new v olume gro up. Example # mkdir /dev/vg06 4. Use th e ls âl command (wit h the output pi ped to gr ep to displa y only the fil es containi ng âgroupâ) t o display the minor nu mbers f or the exis ting group fi les. Example # ls â1 /dev/vg* | grep group crw-rw-rw 1 root root 64 0x0000000 Nov7 08:13 group : 5. Choose a unique minor numb er for th e new group file in sequ ential order (for exa mple, when exi sting volume gro ups are vg00-vg 05 and the next group name is vg06, use m inor nu mber 06 for t he vg06 gro up file). The mino r numbers ar e hexadecimal (for example, the 10th minor number is 0x0a0000 ). 6. Use mknod to c reate the gr oup file for the new director y . Specify th e volume gro up name, major number , and minor numbe r . The major number for all grou p files is 64.
Installation 43 Example In th is exampl e: gro up name = vg0 6, major nu mber of group file = 64, minor number of existing gr oup file = 06 (which must be uniqu e for each volume group) , and c = chara cter . # mknod /dev/vg06/group c 64 0x060000 : 7. Create t he volume group. T o allo cate more than one physical vol ume to the new vol ume group, add the o ther physica l volumes, separat ed by a space. Example # vgcreate /dev/vg06 /dev/dsk/c6t0d0 Volume group "/dev/vg06" has been successfully created. Volume group configuration for /dev/vg06 has been saved in /etc/1vmconf/vg06.conf. For Log i cal Unit Siz e Expansion (LUSE) volumes th at contain mor e than 17 OPEN- 8/9 LDEVs or more than 7 043 MB (OPEN-8/9*n -CVS), use th e âs and âe physical exte nt (PE) para mete rs of th e vgcr eate command. See âLUSE device parame tersâ (pag e 68) . If you need to de lete a volume g roup, use the vgr emove command (for example, vg remove /de v/vgnn ). If t he vgr emove command does not work becau se the volume gr oup is not ac tive, use t he vgexport command (for example, vgexpor t /dev/vgnn ). 8. Use th e vgdis play command to ver ify that the ne w directory was cre ated. 9. Use vgdi spl ay âv to verify t hat the vol ume group was created co rrectly .

Glossary 79 LDEV Logical d evice. An LDEV is creat ed when a RAID group is ca rved into pi eces accordi ng to the select ed host emulat ion mode (t hat is, OPEN-3, OPEN-8 , OPEN-L). T he number of res ulting LDEVs depends on the select ed emulati on mode. The term LDEV is often used synonymou sly with t he term volume. LUN Logical unit number . A LUN resul ts from mapp ing a SCSI logic al unit number , port ID, and LD EV ID t o a RAID group. The si ze of the LUN is determin ed by the emulat ion mode of the LDEV and the number of LDEVs associa ted with the LUN. For exampl e, a LUN associate d with two OPEN- 3 LDEVs ha s a size of 4,693 MB. LUSE A LUN is normally a ssociat ed with o nly a s ingle L DEV . The LUSE f eatur e allows a LUN to be a ssociated wi th 1 to 36 LDEVs. Essential ly , LUSE ma kes it possi ble for applica tions to access a single la rge pool of st orage. The LUSE featur e is available when the HP S t ora geW orks LUN Configurati on Manager produ ct is insta ll ed. OFC Open Fibre Control.

Exce pt for OPEN-V , the se devices are ba sed on fixed sizes. OPEN- V is a user -defined size. Support ed emulati ons include OPEN-3, OPEN-8, OPEN-9, OPEN-E, OPEN- L, and OPEN-V device s. ⢠LUSE devices (OPEN- x *n ): Logical Uni t Size Expansion (LUSE) devices combine 2 to 36 OPEN- x devices to c r eate expanded LDEVs lar ger than s tandard OPEN-K/3/ 8/9/E disk devic es. For example, a n OPEN-x LUSE volume create d from ten OPEN-x volumes i s designated as OPEN-x*10. ⢠CVS devices (OPEN-x CVS): V olume Size Conf iguration ( VSC) defines custom volu m es ( CVS) that are s maller than n ormal fixed- sized logica l disk dev ices (volumes ). (OPEN-V is a CVS-based c ustom dis k size that you dete rmine.

The physica l volumes that make up one volu m e group c an be located either in the same disk arra y or in other disk arrays . T o allo w m ore volume groups to be created, use SAM to modi fy the HP-UX sys t em kernel confi guration. See appendix C (page 73) fo r details. T o cre ate volume gr oups: 1. Use th e vgdis play command to dis play the exist ing volume group s. 2. Choose a unique name for the new volume gr oup (f or exa mple: vg06). 3. Create t he director y for the new v olume gro up. Example # mkdir /dev/vg06 4. Use th e ls âl command (wit h the output pi ped to gr ep to displa y only the fil es containi ng âgroupâ) t o display the minor nu mbers f or the exis ting group fi les. Example # ls â1 /dev/vg* | grep group crw-rw-rw 1 root root 64 0x0000000 Nov7 08:13 group : 5. Choose a unique minor numb er for th e new group file in sequ ential order (for exa mple, when exi sting volume gro ups are vg00-vg 05 and the next group name is vg06, use m inor nu mber 06 for t he vg06 gro up file). The mino r numbers ar e hexadecimal (for example, the 10th minor number is 0x0a0000 ). 6. Use mknod to c reate the gr oup file for the new director y . Specify th e volume gro up name, major number , and minor numbe r . The major number for all grou p files is 64.

Create t he volume group. T o allo cate more than one physical vol ume to the new vol ume group, add the o ther physica l volumes, separat ed by a space. Example # vgcreate /dev/vg06 /dev/dsk/c6t0d0 Volume group "/dev/vg06" has been successfully created. Volume group configuration for /dev/vg06 has been saved in /etc/1vmconf/vg06.conf. For Log i cal Unit Siz e Expansion (LUSE) volumes th at contain mor e than 17 OPEN- 8/9 LDEVs or more than 7 043 MB (OPEN-8/9*n -CVS), use th e âs and âe physical exte nt (PE) para mete rs of th e vgcr eate command. See âLUSE device parame tersâ (pag e 68) . If you need to de lete a volume g roup, use the vgr emove command (for example, vg remove /de v/vgnn ). If t he vgr emove command does not work becau se the volume gr oup is not ac tive, use t he vgexport command (for example, vgexpor t /dev/vgnn ). 8. Use th e vgdis play command to ver ify that the ne w directory was cre ated. 9. Use vgdi spl ay âv to verify t hat the vol ume group was created co rrectly .

Any fi le system att ached to the logical volu me must be unmount ed before exec uting the lv remove command. Example: lvremove /dev/vgnn/lvolx lvext end Incr eases the si ze of an exis ting logical vo lume. Example: lvextend âL size /de v/vgnn/lvolx lvr educe Decrease s the size of an existing lo gical volume. Any fi le system att ached to the logical volu me must be unmount ed before exec uting the lv reduce co m mand. Example: lvreduce âL size /de v/vgnn/lvolx Cau ti on Data withi n the file system can be l ost after exec ution of lvre duce . Create l ogical volume s after you c r eate volume group s. A logical vo lume must be cr eated for each n ew SCSI disk devi ce T o c reate l ogica l vo lum es : 1. Use th e lvcreat e âL command to crea te a logical volume. Specify the volume siz e (in megabytes ) and the volume group for the new lo gical vol ume. HP-UX assigns the l ogical volu m e numbe rs auto m atical ly (lvol1, l vol2, lvol3). Use the followin g capacity val ues for t he size para mete r: OPEN-K = 17 40 OPEN-3 = 2344 OPEN-8 = 7004 OPEN-9 = 7004 OPEN-E = 13888

Unlike t raditional SCSI, when contro l of the loop is acquired, a point -to-poi nt connectio n is establish ed from initi ator to t arget . T o enable transpa rent use of F C P , the opera ting system map s a TID to each AL-P A. The host ma ps SCSI protocol to Fibre Chann e l protocol and detect s and acce sses Fibr e Channel-conne cted devices using devi ce files ( /dev/d sk/c*t*d* and / dev/rdsk/c *t*d* ) in the same way as for SCSI-conne cted devices . The device fi les for Fibre Ch annel-connec ted devices are configur ed in a dif ferent way fr om SCSI-connect ed devices , becau se Fibre Channe l supports 12 6 addresses pe r path while S CSI support s 16 TIDs per path. The fo llowing table i dentifies t he fixed mappings bet ween the TID (dr ive) valu es assigned by the ope rating s ystem and the Fi bre Channel na tive addr esse s (AL _P A /SE L_ID ) for F ibr e C han nel a dapt ers. T he co ntr oller number (t he dk s value in /dev/dsk/ dks*d*l*s* ) depe nds on the ser ver configur ation, and a d iffer ent value is assigned per each column .
